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:ο»Ώ
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.
Pneumatic drum mixers require up to 10 CFM of air to operate properly.
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
