MK.59.HF air vent grille system

It is a system of air vent grilles made with ML.59.HF lamellas which finds its application in intake and exhaust vents, stacks, air-conditioner housings, openwork baffles or as a window or technical door filling.


The grate has been designed to fulfill the growing requirements for the ventilation systems with restrictive air flow parameter limits such as active area of 77% or very low air flow resistance. The cutting-edge parameters of MORAD MK-59 HF system have been confirmed by an independent research body.


On customer's request the grilles are available without the anti-insect stainless steel stitch. The grille can be fastened directly using bolts to be screwed through the frame or using anchors. The grilles are available in colours of the RAL colour chart or "raw".

  • Physical cross-section for the internal grille area is 77% while the visual one is as much as 91%.
  • Grille structure is composed of extruded aluminium profiles combined to form a frame with horizontal aluminium bars inside spaced every 59 mm.
  • We can make the grilles in size range from 300 x 300 mm to 5m2 (with even the largest size being without a substructure). Larger grilles will require an additional supporting structure.
  • With the knowledge of the pressure drop characteristics as a function of the inlet velocity we can precisely select a grille in the ventilation industry.
