T-Bolt III Compressor System


What makes the BEST dental air compressor?

...the answer is simply clean air

Clean air comes down to reliability and filtration.  Out of our multiple filtration points, the most unique is the .01 micron filter.  It makes the air virtually 100% free of oil and removes moisture during periods of high humidity.  Most impressively, it removes particulates down to virus size!

That is why the T-Bolt III is the whole package and the right choice for clean air...

Clean, Quiet and Time-tested Durability.







The T-Bolt III dental air compressor outperforms and outlasts competing compressors...

  • The T-Bolt III is inherently quiet, while competing compressors usually require sound coverings.
  • Many compressors use much more power to produce less air than the T-Bolt III.
  • Other compressors have a shorter life expectancy of only 5-10 years.
  • Unlike the T-bolt III, other compressors are built with components that can rust and eventually fail.
  • Inadequate filtration is a major pitfall in competing products.
  • Other compressor designs are subject to burnout if excessive facility leakage occurs.
  • Many similar products are limited to 80/100 psi differential range.
  • Sometimes competitors require multiple models and features to do what the T-Bolt III does.

also keep in mind...

  • In other systems, the motor and compressor are an integral part of each other. Lose one, lose both.
  • Similar compressors consume large amounts of oil with age.
  • Other compressors can pump oily, dirty and moist air directly into the tank, creating an environment that promotes rust and bacteria. 
  • Some offer refrigerant dryers at an extra cost.  This technique offers less-than-desirable dew point temperature that is worsened if residual oil is not removed prior to drying.

Before deciding on a compressor, ask yourself...

How clean is your air...or the competition's?
We have seen that other systems generally offer between 25 and 40 micron filtration, but often not smaller than 5 micron.  Our filtration of .01 micron is 4,000 times smaller than 40 micron.  For a visual reference, if a .01 micron particle is represented by a golf ball, then a 40 micron particle would be larger than a football field!

If competitors' systems have parts that can rust, how are they cleaned if they do?  Rust will end up in the tank and air...potentially causing a major failure.
The T-bolt III dental air compressor is as close to 100% rust-proof as an air system can be.  Even the fasteners (screws, nuts, etc.) are stainless steel and ideal for humid areas.  Our stainless steel storage tank with a clean-out/inspection cover is another great feature.  If the air system fouls for any reason, the cover allows access for cleaning the tank, and the stainless steel is rust-free for life. 

Is your air dry?
All drying units handle moisture in aerosol and liquid form.  Our stainless steel drying tower maintains correct temperatures in the drying process to give optimum drying at all times.  Many other systems do not maintain that condition while operating at or beyond their maximum designed output and produce extremely high temperatures.

Take “control” of your air quality.
Our control systems are a little more complex than those on most air systems, yet they last longer.  The critical components on most air systems are: the main on/off switch, the pressure switch and/or the power switch for cycling, the centrifugal switch contacts and the motor capacitors.  All T-Bolt III controls are 24 volts, including the pressure switch and centrifugal switch, which extends the component's life indefinitely.  Our techniques for the high voltage on/off of the motor during cycling have minimized or virtually eliminated arcing in the circuitry.

Oil is the lifeblood of a motor. Do you know when to change it?
Inevitably, oil used to lubricate automobile engines or air compressors will break down from high temperature usage, lose its ability to lubricate and have to be changed.  Our high quality oil is designed for the harshest conditions and highest performance.  It is recommended for 2000 hours of use, and we use the compressor's built-in hour meter to determine when the oil is to be changed.

Turn up the heat!
The 24-volt over-temperature switch on the underside of the T-bolt III protects against burnout.  Thanks to this protection, the T-bolt III is not subject to burnout even if a break in a facility line occurs which allows the compressor to run continuously or from:

  • High ambient temperature (installation in non-vented closets, heater rooms, etc.)
  • Low oil level
  • Continuous usage

Does the competition need a boost?
With a 2 horsepower, single phase, 208/230V motor, the T-bolt III does not require a buck booster if the incoming voltage remains stable.  Other air systems will not run on a voltage range that wide.  The T-Bolt III compressor/motor package is so efficient that it is even economical for the single doctor operatory; even more so in a 3 doctor/3 hygienist facility.

Time for a mechanic or DIY.
The T-Bolt III compressor/motor package is flange mounted and externally coupled to facilitate servicing.  The compressor head can be completely replaced in approximately 15 minutes.  The motor can be replaced in approximately 30 minutes.  Most dental compressors have a common shaft for the motor and compressor.  If either the motor or compressor head fails, you lose both, which makes the repair cost astronomical!  We believe that the coupling approach and the projected longevity of the T-Bolt III components make our configuration much more desirable.

Let's trim the fat.
The T-Bolt III dental air compressor, at 135 lbs., is the lightest compressor to provide what we can in this compact package.  This is much more desirable than wrestling similar models that can weigh up 800 lbs.

Waste management...who empties the trash?
The T-Bolt III has a muffled, flexible drain line for handling the oil, moisture and contaminants removed from the compressed air.  This line can be drained into a sewer/waste drain or suction system for maximum cleanliness.  Other systems simply dump the waste into a tray that you must handle and empty.


Are you new to dentistry or the idea of a precision air compressor?  Let us break things down for you...

 A basic air system consists of three parts: an air compressor, pressure switch and a storage tank.

Reciprocating Compressors:

Most air compressors are reciprocating types.  The oil-less reciprocating type is noisy, and the oil bath type tends to overheat and wear if demand requires operating for long durations.  Oil consumption increases throughout the life of the compressor...much the same as in an automobile.  Almost immediately, the oil being consumed will pass directly into the air supply.  Many compressors of this design require 40% “off” time to prevent over-heating and maximize longevity.  This means that only 60% of its rated CFM output is available over a period of time.

Pressure Switches:

Pressure switches generally cycle the system pressure between 80 and 100 PSI with a 20 pound differential.  This guarantees a continual tank pressure of 80 PSI.

Storage Tanks:

The storage tank is simply that; a pressure vessel that holds air.  Most tanks, while coated or line, are invariably made of material that rusts.

Add-on Features:

A basic air line filter added between the compressor and tank will remove water droplets only without substantially reducing the dewpoint.  It will remove dirt particles down to the rated size of the filter element; generally 25 microns.  An oil filter added between the compressor and tank will remove most of the oil transferred into the air lines from the compressor but will have no effect on the moisture in the air supply. 

To combat moisture, some systems rely on a form of “dryer.”  Refrigerant dryers are normally an add-on for existing or new installations. Their only function is to remove moisture.  They are generally installed in the line as if it comes out of the tank and require electricity to function, which increases operating costs.  This type of installation still results in moist air being stored in the tank.  The storage tank must then be drained regularly but is still subject to rust and corrosion.  Refrigerant dryers can only reduce the dew point to just above 32 degrees F.  This may not be sufficient in cold climate areas.  A desiccant dryer system is usually a single tower mounted between the compressor and tank.  The drying media inside the tower should absorb moisture and oil.  The pressure in the tower is reduced to room pressure each time the compressor shuts off or unloads, and this type of air dryer is capable of reducing the dew point to well below zero degrees F.  A gentle reverse flow of stored, dry air removes excess moisture from the tower and exhausts it to a drain. Most towers are made of a material that can rust or corrode, and excessive oil contamination will shorten the effective life of the drying media as it can not regenerate.

Additionally, a drain would benefit the system, but a manual drain requires constant attention.  An automatic drain is convenient, but can eventually stop draining due to excessive contamination.  That requires dis-assembly and cleaning.

What did we learn from this assessment?

This air system described above will supply dirty, wet and oily air.  Much of this will remain to contaminate and eventually rust the storage tank while destroying operatory instruments and equipment.

An awareness of the above, and the existence of the Hydrovane rotary compressor, guided us in the development of the finest air system available for the dental profession.  This development of the T-Bolt III dental air compressor includes:

A compressor that will last the life of a dental practice with minimal maintenance.

  1. Oil transfer will remain extremely low
  2. Compressor runs continuously- reducing operating costs.
  3. It produces 160% more air in a given period of time than a comparable reciprocating unit that requires 40% more “off” time than the rotary.
  4. It is quiet

Copper coils between compressor and filter reduce air temperature to make filter and dryer more effective.

An air filter with 5 micron element to remove water droplets and dirt particles.

  •  It is back-flushed and drained each time the system unloads
  •  Moisture is purged from the drying tower, down through and out the filter by quickly purging the air in the drying tower
  • The drain line can be placed in any drain from floor level up to 3 feet high
  • The filter should not require attention for long periods of time

A stainless steel drying tower with a desiccant drying media capable of removing moisture and lowering dew point to a sufficient level for virtually any climate.

  • A gentle back flow of dry air continues to regenerate the desiccant each time the system unloads
  • The desiccant should last a minimum of two years and changed only when overly contaminated with oil
  • Tower removal and drying media replacement is simple and easily accomplished
  • The oil removal is a bonus that is not possible on a refrigerant dryer system without adding a separate oil filter

Differential pressure controls maintain the tank pressure between 100 and 120 PSI.  A secondary function of this control actuates the filter and drain controls while regenerating the drying tower media.

A 10 gallon stainless steel storage tank beneath the compressor stores clean, dry, oil-free air.

  • It has a clean-out cover that is easily removed.  This allows for periodic inspections to ensure that dryer is functioning properly
  • A pressure relief valve in the tank cover serves as a backup to the the relief valve in the compressor

One final thought...

Compressed air is the very heart of every operatory, therefore, do not allow the initial cost of a quality air system be a factor in selecting which one to buy.  The system should be economical to operate and be selected to protect as well as operate your various air-operated instruments and equipment.  The stored air should be clean, dry and oil-free when the system is new and remain that way 10, 20 or 30 years down the road.
