Circular air transfer grilles for services

Description PYROGRILLE air transfer grilles are manufactured from high performance intumescent slats, spaced 12mm apart. The thickness of the units are 38mm. Performance PYROGRILLES have been subjected to fire resistance tests in accordance with BS 476 Part 20 : 1987 and assessed to Dutch Norm NEN 6069. Applications PYROGRILLE dampers must be secured within the ducting using 4 self tapping screws. On circular PYROGRILLES the screws should pass through the aluminium rings on the outer part of the PYROGRILLE. Clearance gaps should be sealed using PYROMAS A intumescent sealant. Gaps around the PYROGRILLE unit greater than 3mm should be fire sealed using PYROMAS A intumescent sealant. Finishes Standard colour black. Maintenance Since there are no moving parts to go wrong, PYROGRILLES are easily maintained. Units should be cleaned using a damp cloth. Grease can be removed by using neat liquid detergent or methylated spirit. Strong degreasing agents should not be used nor should the units be immersed or saturated with water. Ordering When ordering please state, fire resistance required. Circular PYROGRILLE’s are available in standard sizes of 100mm, 125mm, 150mm and 200mm. Non-standard sizes available on request.
