RAM standard blowers feature a piston ring system between thecompression chamber and vent cavities. This models’ vent cavities are plugged for purge or drain. Special long-life mechanical seals with Viton™ O-rings are installed at each bearing to control gas and oil leakage. The seal incorporates a proprietary geometry that promotes enhanced cooling and extended life. RAM gas units are suitable for both vacuum or pressure service. Alternate materials and optional O-ring material are available for these machines.
RAM-VJ Water Sealed WHISPAIR Vacuum Blower
