Key Features
Air leakage with back pressure to EN 1751, class 4
Maximum differential pressure: 5000 Pa
Differential pressure can be adjusted from 50 – 1000 Pa (B > 600 mm: 600 Pa max.)
Blades made of aluminium, casing made of galvanised steel Blades open when the maximum differential pressure is exceeded and close automatically when the pressure drops
Blade locking with a permanent magnet
Robust, maintenance-free construction
Available in standard sizes and many intermediate sizes
Operating temperature 0 to 80 °C
Optional equipment and accessories
Installation subframe
Powder coating (RAL or DB)
Stainless steel construction with stainless steel casing; blades made of aluminium
Application
Pressure relief dampers of Type ARK2 for the protection of internal spaces from differential pressures in excess of set maximum levels
When the set maximum differential pressure is exceeded, the blades automatically open to relieve the excess pressure
Pressure peaks will be reliably controlled Differential pressure can be adjusted from 50 – 1000 Pa (B > 600 mm: 600 Pa max.)
Special characteristics
Robust, maintenance-free construction
Maximum differential pressure: 5000 Pa
Air leakage with back pressure, in closing direction, to EN 1751, class 4
Damper for negative or positive pressure (air extract or discharge)
Operating temperature 0 to 80 °C
Maintenance-free DU bearings with Teflon coating, bearing shafts made of stainless steel
Each blade is locked with a factory set permanent magnet
Adjustable differential pressure for blade opening: 50 – 1000 Pa, depending on width
Nominal sizes
B: 200, 400, 600, 800, 1000, 1200 mm (intermediate sizes: 201 – 1199 mm, in increments of 1 mm)
H: 345, 675, 1005, 1335, 1665, 1995 mm (intermediate sizes 355 – 505, 685 – 835, 1015 – 1165, 1345 – 1495, 1675 – 1825 mm in increments of 1 mm)
