The FPS 55 Series is designed as an add-on unit for mobile equipment.


FPS 55.1

This compact unit is easy to install and requires minimal space.

  • Heavy duty powder coated metal construction
  • 12 or 24 volt DC or 115 volt AC
  • CAF47R high efficiency particulate/vapor filter
  • Pre-cleaner options
  • Centrifugal pre-cleaner
  • Motorized Centrifugal pre-cleaner
  • Differential pressure gauge to ensure pressurization

Every FPS 55 series pressurizer is factory vapour tested for integrity utilizing CAFs patent pending test procedure.

Our FPS units are designed to pressurize your environment with clean filtered air.

Do you need to remove volcanic ash?
Do you have an older cab with no filtration system?
Is your cabs filtration system inadequate?
Do you have a control room or office that is contaminated with dust or vapors?
Do you want to improve the air quality in your home?

Consider a Filtration / Pressurization System (FPS) from Clean Air Filter

Clean Air Filter has utilized the latest in technology and research in developing the ultimate in air filtration to create a cleaner healthier environment. There are many models to choose from to suit your needs


Airflow through the CAF FPS55 Series system is as follows:

1. Contaminated air is drawn into the system through the centrifugal pre-cleaner. The   circular motion of the pre-cleaner separates out larger particulates dramatically increasing filter life.

2. Air passes through the 3 stage primary filter.

Stage 1 is a PAPER MEDIA particulate filter designed for the heavy dust environment of agricultural, industrial, mining, and off-road conditions.
Stage 2 is respirator grade ACTIVATED CARBON.  The porous nature of this media effectively adsorbs organic vapors such as diesel and chemical fumes.  Activated carbon works on surface area and CAF’s patented design maximizes this principle.  Specialized carbons are available for specific vapors.
Stage 3 is a HEPA sub-micron FINAL FILTER.


Air exiting the FPS unit creates positive pressure inside a properly sealed cab. This over-pressure pushes clean air out leaks in the positive pressure side of the system, rather than allowing contaminated air to enter.  A differential pressure gage is available to measure the difference in pressure between the inside and outside of the cab.
CAUTION: The cab MUST have positive pressure.  CAF has observed respirator protection levels in cabs with as little as 0.02” of cab pressure. Standard: EN15695 requires a minimum cab pressure of 0.08” of water.
The FPS55 Series is a compact unit that is easy to install and requires minimal space.
Every FPS55 series pressurizer is factory vapor tested for integrity at .00038 micron utilizing CAF’s patented test procedure.
This same procedure, along with particulate testing, can be used to completely characterize environmental enclosures in the field, (CDC Mining Publication).
CAF has proven technology with over 25 years of experience.
