High Pressure Industrial Blowers Model 1200 Heavy Duty Bi-directional Rotation 19 Series - Horizontal Air Flow 86 Series - Vertical Air Flow 55 Series - Horizontal Flow, Single Envelope Gas Service 82 Series - Vertical Flow, Single Envelope Gas Service 66 Series - Horizontal Flow, Double Envelope Gas Service 69 Series - Vertical Flow, Double Envelope Gas Service Model 1200 PD PLUS heavy duty industrial blowers are designed for high performance applications, up to 15 PSIG pressure boost or 15” Hg dry vacuum (24” Hg water injected). 19/86 Series This series has wide application in pneumatic conveying, wastewater treatment and the general process industry where high pressure, high volume air is required. Seal areas are vented to atmosphere to relieve process pressure against the internal lip seals, and to provide oilfree air. 55/82 Series (Single Envelope Gas Service) This series is utilized in such applications as closed loop pneumatic conveying, process gas handling, or elevated pressure applications up to 100 PSIG discharge. Vent openings are tapped and plugged to prevent gas leakage. These fittings can also accept an inert gas purge for positive containment of the process gas. 66/69 Series (Double Envelope Gas Service) This series is built to laboratory standards where virtually complete sealing is required. In addition to the features shown on the 55/82 series, the drive shaft is mechanically sealed and the oil sumps are plugged to provide an even higher degree of leakage protection. Material Specifications: Housing: Cast iron End Plates: Cast iron End Covers: Cast iron Rotors: Ductile iron Shafts: Ductile iron cast integrally with rotor Bearings: Rotor shafts - Double row ball Drive shaft - Spherical roller Drive Shaft: SAE 4140 forged alloy steel Gears: Heat treated alloy steel, helical cut Seals: 19/86 - Lip and labyrinth type on the rotor shafts; lip seal on the drive shaft 55/82 - Mechanical and labyrinth type on the rotor shafts; lip seal on the drive shaft 66/69 - Same as 55/82 plus mechanical sealing on the drive shaft Lubrication: Bearings are lubricated by an integral pressure system including filter and oil to water heat exchanger; gears are splash lubricated. For elevated pressure applications, 55/82 series and 66/69 series are available with high pressure sealing and testing to allow discharge pressures as high as 100 PSIG (up to a 15 PSI maximum pressure boost)* * Blowers operating with a discharge pressure above 20 PSIG require mechanical rotor shaft sealing; above 25 PSIG requires hydrostatic testing and special high pressure seal leakage testing. Model Size All PD Plus blowers are factory tested to meet ISO 9001 registered quality standards. Rotors are dynamically balanced to meet ISO1940 Grade 6.3 specifications.
