Semco RV-15 Rotary Airlock | 304 Stainless Steel

New Old Stock (NOS) | High-Capacity 1.5 CFR | Outboard Bearing Design

This is a rare opportunity to acquire a New Old Stock Semco RV-15 at a significant discount compared to current factory lead times and pricing. This unit has never been installed or used in production. It features a 304 Stainless Steel housing and rotor, making it ideal for food-grade, chemical, or pharmaceutical applications where corrosion resistance and product purity are paramount.

Key Features & Performance Highlights

• Pristine Stainless Steel Surfaces: Because this is a New Old Stock unit, the 304 SS housing and rotor vanes are free from the pitting, wear, or "scoring" typically found on used airlocks. It maintains factory-tight tolerances for maximum pressure sealing.
• Outboard Bearing Protection: Designed with bearings mounted away from the main housing. This "Style 1" configuration prevents product contamination and ensures that heat from the process does not degrade the bearing lubricant, significantly extending service life.
• High-Efficiency 8-Vane Rotor: The 8-vane design provides a minimum of two vanes in contact with the housing at all times, ensuring a superior air seal in pneumatic conveying systems (both pressure and vacuum).
• Adjustable Rotor Tips: (If applicable) Equipped with adjustable/replaceable tips to maintain a precision seal as the unit ages, reducing air leakage and energy costs.
• Heavy-Duty Industrial Housing: The RV-15 is built with thick-wall stainless castings, engineered to handle heavy abrasive loads or corrosive environments without warping or losing structural integrity.
