Uniform wind pressure with PA plate-bellows spring.
Because of its geometrical design, this bellows spring maintains a uniform pressure on the bellows plate. When mounted very flat, there is actually a slight increase in pressure.

Length approx. 200 mm, width approx. 100 mm, mounting height between 65 and 120 mm to suit individual circumstances.

Also ideal for improving existing wind systems.

Sample spring and price each (min.10 off) deliverable.
