Step 3: Choosing the Proper Size Air Compressor

Profoam rigs come standard with industrial-grade rotary screw air compressors for our electric compressor units. Rotary screw compressors are built to last and outperform conventional reciprocating air compressors due to their 100% duty cycle and simplistic design. The larger the compressor, the more CFM of air it will produce. All SPF rigs require compressed air to drive the material transfer pumps and spray gun. 15 CFM of air can run these two components sufficiently. However, when adding additional pneumatic components, your spray foam rig will require additional CFM of air. For example:

Pneumatic Proportioners:

Air-driven proportioners rely on compressed air to drive the proportioning pumps and can require up to 35 CFM of air for the machine alone.

Drum Mixers:

Pneumatic drum mixers require up to 10 CFM of air to operate properly. 

High-Pressure Fresh Air System:

Some customers may choose to upgrade their fresh air respirator to a High-Pressure System. These systems require up to 15 CFM of air to operate 

Your Profoam sales professional will be able to guide you in choosing the proper size air compressor for your mobile spray unit.

All Profoam Rigs come standard with a High-Temperature Refrigerated Air Dryer
