VRL1 volume flow limiter
Volume flow limiters VRL1 are mechanical, maintenance-free controllers for position-independent insertion into ventilation ducts. They keep volume flows constant. The casing is encapsulated and protects the control mechanism from contamination; the encapsulation is completed by lip seals on both sides. The VRL1 meets the highest hygiene requirements thanks to its antistatic and microbe-resistant material.
Technical details

Declarations & proofs
Product details
Volume flow limiters VRL1 are maintenance-free, mechanical volume flow controllers for position-independent insertion into round air ducts. They operate without external energy and maintain the set volume flow automatically and constantly with high control accuracy. They are suitable for use in both supply air and exhaust air.
Maintenance-free design
The controllers have an encapsulated casing, which protects the control mechanism from contamination.
Design of the VRL1 volume flow limiter
Mechanical volume flow limiters VRL1 are made of antistatic and microbe-resistant material. VRL1 volume flow limiters therefore meet the highest hygiene requirements.
Size range and pressure ranges
VRL1 volume flow limiters are available in sizes DN80 to DN250 and are designed for a pressure range from 30 Pa to 300 Pa.
Product markings
This product has an Environmental Product Declaration (EPD) and has been awarded a hygiene certificate by an independent testing institute.
