Compensating connectors

Compensating connectors for use in HVAC systems and equipment. Suitable for use in hygiene applications.
Awarded the TÜV seal of approval (see multi-blade dampers for TÜV certification).

Compensating connector type I

Frame: Aluminium profile Rubber insulation: 30 x 20 mm Depth:     110 mm, total depth 130 mm Coupling flange: 30 mm

Compensating type II

Frame: Aluminium profile Rubber insulation: 30 x 20 mm Depth: 150 mm Coupling flange: 30 mm

Pre-assembled compensating elements are supplied for mounting at the corners of the connectors. Connectors 1000 mm in length or longer come with an additional borehole in the middle of each side for fitting of further elements.
