Roots RAM Series units are recognized by many as the most volumetrically efficient blowers in the industry. Unless otherwise noted, RAM Series units can operate under vacuum or pressure without equipment modification, and can provide vacuum and pressure simultaneously for a single unit system.
RAM Series units have integral shaft ductile iron impellers with wrap-around profiles. The heads and rigid housing are gray cast iron, while the shaft end and gear covers are aluminum. Carburized and ground alloy steel timing gears are securely mounted on bevel shafts. All RAM series units feature cylindrical roller bearings and splash lubrication for maximum life. Mounting brackets are steel and removable allowing adaptability to vertical or horizontal installation depending on requirements.
Piston shaft seals reduce gas leakage through the head plates, while oil seals maintain lubrication in the bearings. RAM line units are splash lubricated on both sides with high volume oil reservoirs and accurate sight glasses.
All standard units are center oriented to allow rotation in any direction.
RAM-J units feature the original WHISPAIR jets to control pressure equalization by feedback in the direction of impeller movement.
The Whispair function results in unidirectional flow and rotation of the drive shaft.
Standard RAM blowers have a piston ring system between the compression chamber and vent cavities. The vent cavities of these models are connected for purging or draining. Special long-life mechanical seals with Viton™. O-Ring seals are installed in each bearing to control gas and oil leakage. The seal incorporates a patented geometry that promotes improved cooling and extended life. RAM gas units are suitable for vacuum or pressure service.
Whispair feature results in unidirectional flow and drive shaft rotation.
These units are equipped with an inlet spray nozzle and flow meter for water injection. This feature cools the unit allowing deeper vacuum levels than are possible with conventional positive displacement vacuum blowers.
This dry RAM WHISPAIR is a high pressure blower featuring a jet discharge plenum designed to allow externally cooled gas to flow into the casing and the Whispair™ jets control pressure equalization. The system operates up to a pressure of 30 psig (2068 mbar) and has a flow capacity of 520 cfm (885 m3 / h).
This dry exhauster features a jet plenum designed to allow fresh, atmospheric air to flow into the casing. This design allows continuous operation at white-out levels in a single unit working scenario. The RAM-DVJ is capable of achieving a vacuum of up to 27” Hg (910 mbar) and a flow rate of 2400 cfm (4077 m3/h).
