Spirax Sarco S7 Carbon Steel Separator DN65 to DN350 – IBR Certified Baffle Type
Spirax Sarco S7 carbon steel separator for steam, air & gas systems. IBR certified, DN65-DN350, ASME 150/300 flanges. Buy from PC Engineering India.
Overview
The Spirax Sarco S7 is a baffle-type separator engineered for efficient removal of entrained liquids from steam, compressed air, and industrial gas systems. Constructed entirely from carbon steel, this separator is designed for demanding process environments where moisture carryover can damage downstream equipment or compromise product quality.
The S7 operates by forcing the flow through internal baffles that create velocity changes, causing entrained liquid droplets to separate from the main flow. Collected condensate or liquid is then drained via a suitable steam trap (FT series with air vent for steam service) or liquid drainer (CA series for air/gas service). This makes the S7 an essential component in steam distribution systems, compressed air networks, and process gas lines.
This separator fully complies with Indian Boiler Regulations, 1950, and is available with IBR certification and manufacturer's Typical Test Report—critical documentation for regulated industrial installations across India.
