Round Exhaust Chimney 710mm

Our Round Exhaust Chimney is a versatile, high performing unit that is available for both new installations as well as retrofits with round or square apertures. Constructed from UV stabilized GRP ensuring that it will not rot and lasts the rigours of pressure cleaning. The internal butterfly valve features stainless steel fixings improving its corrosion resistance while diverting rain when not in use. Manufactured from UV stable GRP, it does not rot or go brittle over time. This, combined with its seamless construction facilitate pressure cleaning whilst being impervious to rain, sun wind and hard frosts.

Our chimney features a lightweight, tough GRP butterfly valve featuring stainless fixings that result in a waterproof seal when the fan is off, diverting rainwater back onto the roof sheet by design. This design lowers installation and operational maintenance costs by not needing an electrical actuator to operate. We have extensively tested the performance of these units in our wind tunnel and on farm to confirm the high performance and suitability of these units for British farming.
