Sealey SAC42755BLN Air Compressor 270L Belt Drive 5.5hp 3ph 2-Stage with Cast Cylinders Low Noise is a heavy-duty, low‑noise compressor for garage, bodyshop and industrial use. A 5.5hp 3‑phase motor with soft start drives a 2‑stage pump delivering 21.1cfm (598L/min) displacement and 15.3cfm (434L/min) free air delivery at up to 145psi (10bar). Cast iron cylinder heads enable slower running and longer pump life. The fully enclosed, insulated design reduces noise to just 69dB(A) at 1m and protects vital components from damage. A 270L receiver provides generous air storage, while an automatic pressure cut‑out switch and tank pressure gauge support safe, easy operation. The control box includes a tachometer for monitoring usage and optimising service intervals. With full CE certification, documentation and a heavy-duty 415V 32A supply requirement, this compressor is ideal for users needing high output with significantly reduced noise.
