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 two top REFINA compressors suited for spray rendering:

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

AC 134E 134CFM Compressor (Twin Motor): This twin-motor compressor provides 134 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.
