Filtration cart examples

PO filter cart will process 3200 c.f. of air. In a Oceans 4.9 c.f.m. =294 c.f. per hour hence cart is changed every 11-12 hours under most dry conditions of ambient environment based on filling Aluminum 80 c.f. cylinders that have appx. 500 psi at the start of the fill process.

P31 filter cart will process 11760 c.f. of air. In a DMT 08 8.4 c.f.m = 500 c.f. per hour hence a cart is changed every 24 -26 hours under most dry conditions of ambient environment based on filling a Aluminum 80 c.f. cylinder that has appx. 500 psi at the start of the fill process.

P41 filter cart will process 28,700 c.f. of air. In a DMT 08 8.4 c.f. = 500 c.f. per hour hence a cart is changed every 57-60 hours under most dry conditions of ambient environment based on filling a Aluminum 80 c.f. cylinder that has appx. 500 psi at the start of the fill process.

P 2 filter cart will process 40,000 c.f. of air. P2 Securus cart will process 67,000 c.f. of air.

The above is a general recommendation; refer to your instruction manual for the exact answers.

Common question related to small compressors powered by generators:

The formula used to determine compressor capacity is: C = V/(Kp*T) where:

C = capacity in SCFM (Standard Cubic Feet Per Minute Intake)

V = volume in cubic inches

Kp is a constant depending on operating pressure (.26 for 2000 psi)

T is the shooting interval in seconds

Compressor
Under normal conditions, the following information about the compressor will provide satisfactory guidelines for selecting the right compressor for your needs. Unusual operating conditions may require a larger unit than indicated. If you are not certain, select a larger unit to ensure adequate initial capacity and provide for future needs.

Power Source
It is very important to determine the correct electrical service available to your location. Make certain the compressor you have selected will have the correct power available for proper operation. Incorrect voltage or phase will delay installation. Contact a professional electrician to determine the electrical services in your facility. Gasoline or diesel engines are available if a mobile unit is desired over a stationary design. Chart A illustrates the proper electrical service required for a high pressure breathing air compressor.

Compressor Air Intake Requirements
It is important to provide fresh, uncontaminated air to the compressor’s intake. Gross containment of intake air will adversely affect the efficiency of the purifier, for instance:
If the compressor is operated near running vehicles or close to a gas heater, the CO and CO2 levels in the ambient air may be affected and will have an adverse impact o the air quality output by your system. If the compressor is located in a room where chemicals are stored, fumes or particles can be drawn into the system and affect air quality. Your compressor should never be located where volatile gases can enter the compressor.
