The Alkin W31 Mariner 3.7 CFM Vertical Compressor is a premium, high-pressure air solution built for reliability, performance, and long-term durability. Designed with a compact vertical footprint, this compressor saves valuable floor space while delivering powerful output for demanding applications.
At the heart of the W31 is a three-stage, low-RPM (1050 RPM) reciprocating system, engineered to run cooler, quieter, and longer between service intervals. Capable of producing up to 5000 PSI (345 bar), it provides clean, breathable air that meets EN12021 standards, making it ideal for airgun shooters, scuba, paintball, and professional use.
With a 3.7 CFM fill rate, the W31 offers fast and efficient tank fills, while its integrated P21 filtration system ensures consistent air purity. Built with rugged components like stainless steel intercoolers, aftercoolers, and multi-stage moisture and oil separators, this compressor is made to perform in demanding environments.
