Compressors

Compressors are essential tools that generate and deliver compressed air to power a variety of pneumatic equipment such as spray guns, sanders, and surface preparation tools. They provide high air output and often feature pressure cut-off systems and belt drive designs for efficient, reliable performance. Within the REFINA range, we supply professional-grade compressors and vacuum pumps designed specifically to meet the demands of industry professionals.

Yes, a compressor is required to operate a pneumatic spray gun. The compressor supplies the pressurised air needed to atomise the paint or coating, enabling an even and smooth application. Without a compressor, the spray gun cannot function effectively.

For spray rendering, a compressor must deliver consistent high air volume and pressure to handle heavy coatings. Here are three top REFINA compressors suited for spray rendering:

AC 85 E 8.8CFM Compressor: A super compact, but powerful, portable compressor offering 8.8 cubic feet per minute airflow. Featuring a smaller ait tank, and roll-cage design, whilst being coupled with the same direct-drive design as the AC 88 E. Ideal for small spray rendering projects. Ideal for spraying thin coat top coats renders.

AC 88 E 8.8CFM Compressor: A powerful, portable compressor offering 8.8 cubic feet per minute (CFM) airflow, ideal for medium to large spray rendering projects. Ideal for spraying thin coat top coats renders.

AC 134 E 13.4CFM Compressor (Twin Motor): This twin-motor compressor provides 13.4 CFM, delivering extra power and efficiency for demanding spray applications. Ideal for spraying backing coat renders and more.

Spray rendering typically requires a compressor that can deliver between 40 and 90 PSI to maintain steady pressure and achieve a smooth, even finish. The exact PSI needed depends on the type of spray gun and material being applied.

CFM measures the volume of air a compressor can deliver per minute. It’s a crucial factor because pneumatic tools, like spray guns, require a minimum CFM to operate effectively. A compressor with insufficient CFM will cause inconsistent spray patterns and reduced tool performance, while a compressor with adequate or excessive CFM ensures smooth, continuous operation without pressure drops.
