Functional description
Low-leakage steel doors are low-leakage separating elements for rooms or other enclosures.
When the door is being closed, i.e. when the double locking levers are being turned, the perimeter seal is fully pressed against the frame. As a consequence, the air leakage rate is extremely low even in case of high differential pressures.
Nominal sizes (single leaf) | 400 × 800 to 1100 × 2115 mm |
Nominal sizes (double leaf) | 1080 × 800 to 2280 × 2115 mm |
Maximum pressure on the opening side | 1000 Pa (reinforced construction: 2000 Pa) |
Weighted sound reduction index (with sound absorbing infill) | Single leaf door 43 – 46 dB, double leaf door 44 – 47 dB, doors on both sides of the wall opening 58 – 61 dB |

Low-leakage steel doors as separating elements for walk-in plant rooms, storage rooms, air handling units, filter chambers, or enclosures for machinery or electrical equipment.
Ready-to-install component that consists of a door leaf with double lever locking devices, absorption material, seal and hinges, and a frame.
Air leakage rate on the opening side is approx. 0.6 l/s or 2 m³/h at 1000 Pa (single leaf door).
