What is an access door?

Ventilation access doors are an obligatory component of any well-maintained ventilation system. They are used to give full access to regular maintenance and cleaning of ventilation ductwork for technicians or cleaning professions. 

Access doors are made of galvanized, stainless steel or aluminium sheet. They are available in two basic versions:

  • IPR for round ducts in diameters range 80 to 1600 mm 
  • IPFQ for rectangular ducts.

They are mounted in an assembled duct in which the hole has to be cut according to a delivered pattern.
Each access door is equipped with polyurethane foam ensuring "C" class airtightness.

Access doors - other versions

Optionally, an access door with sealings resistant to +400°C and an access door for insulated ducts are available.
