Damper bodies and blades are made of asbestos-free fire-resistant mineral fibre boards.
Damper bodies and blades can be coated with Promat 2000 anti-moisture coating or Promat-SR
anti-aggressive coating.
The connecting material is galvanised.
According to the customer's request, a stainless-steel damper can be supplied.
Specification of stainless-steel design - division of stainless-steel material:
●
class A2 - food stainless-steel (AISI 304 - EN 17240)
● class A4 - chemical stainless-steel (AISI 316, 316L - EN 17346, 17349)
Everything that is located or enters the inner space or the cross-section of the damper is from a
given stainless-steel material. The parts located outside the body and in the damper mechanism
space are made of galvanised material as standard. In the case of the stainless-steel design, the
cover grilles are always made of galvanised material with a "powder-coated" coating.
Plastic, rubber and silicone parts, sealants, foaming tapes, seals from glass-ceramic materials,
brass housing, sheet bearings, actuators are the same for all material versions of dampers.
Some types of fasteners and parts are only available from one type of stainless steel, this type
will be used in all stainless-steel designs.
The blades and body of the dampers for chemical design (class A4) are always provided with a
coating against the effect of Promat SR chemicals.
Other design requirements are taken as atypical and will be solved individually, according to
customer requirements.
Dimensions are checked with common gauges according to the standard of non-tolerated
dimensions used in air conditioning.
Inter-operational inspections of parts and main dimensions are performed according to the
drawing documentation.
After workshop assembly, a 100% check of the functionality of the closing device and electrical
elements is performed.
