SKU: N/A Category: Brand:

This ultra quiet California Air Tools air compressor is the perfect companion to run our Pneumatic Hash Pump and seriously step up the efficiency of any solventless processing operation. It features a high volume medium pressure pump, 20 gallon tank and is rated to 4 horsepower, all while only producing 75 decibels of sound, which is significantly quieter than your average air compressor. If you’re looking for one that’s even quieter, make sure to check out the in-cabinet version, which drops the sound signature to an incredible 65 decibels (about as loud as your average conversation). These air compressors demand virtually no maintenance due to the oil-free piston construction and are made in San Diego, California.
