Description
Product Part Number
SST-220-2M-IND
Product Overview
The Verplas SST-220-2M-IND Rapid Self-Seal Thermal Flat Channel Duct is a high-capacity insulated ducting solution designed for efficient airflow in low-profile ventilation systems. With a 220mm x 90mm rectangular profile and 2m length, it is ideal for installations where space is restricted but higher airflow volumes are required.
Constructed from graphite-impregnated expanded polystyrene (EPS), the duct provides excellent thermal insulation, helping to reduce heat loss and prevent condensation within the system. The patented push-fit “click and lock” sealing mechanism ensures a secure, low-leakage connection that exceeds industry standards while significantly improving installation speed.
Supplied with an integrated duct-to-duct connector, the SST-220-2M-IND allows for quick and reliable joining between duct lengths. The open end enables direct push-fit connection to 220mm x 90mm fan spigots or fittings, while the duct can be cut to size for flexible installation. Lightweight and easy to handle, it is well suited for MVHR and MEV ventilation systems.
