Benefits

• Noise and Pulsation Control: RAS-J/RGS-J Forty PSL blowers are equipped with WHISPAIR™ jet and integral-shaft ductile iron impellers, offering quieter operation by managing internal pressure fluctuations and reducing energy loss.
• Sturdy Build Quality: Constructed with a rigid one-piece casing, grey iron headplates, and impellers with an involute profile—engineered to deliver strength and long-term performance.
• Advanced Sealing: Includes piston rings and lip-style oil seals to reduce air leakage and stop oil from seeping into the air stream. A hydrodynamic seal at the shaft helps contain lubricant effectively.
• Reliable Lubrication: Alloy steel timing gears are carburized and ground, with splash lubrication applied at both ends for optimal gear and bearing protection.
• Flexible Installation: Rugged detachable steel feet allow for horizontal or vertical setup. Extended shaft options are available to support multiple discharge configurations.
• Warranty Coverage: Backed by a warranty of 24 months from the date of start-up or 30 months from the shipping date, whichever comes first.
