Variable air volume Regulator, model RVV-Q Description Koolair regulators type RVV-Q, are rectangular regulators, and are to be used in variable air volume systems and single duct installations. The RVV-Q consists of a measuring frame with a cross sensor equipped with a differential pressure sensor made of galvanised steel sheet. The regulation damper is made of steel sheet and is provided with sealing lips and side seals to obtain a high level of air tightness. The minimum pressures for equipment setup depend on the actuator sensor accuracy. Applications Regulators type RVV-Q are used to...

VAV regulator, JVR model Description The KOOLAIR JVR variable air volume regulators are rectangular control units for use in variable air volume flow systems and singleduct installations. The regulators consist of an air inlet connection manufactured of galvanised sheet and fitted with a cross-shaped sensor that has differential pressure inlets. The control damper has opposed, aerodynamic blades and is manufactured of aluminium. The damper body includes internal airtight seals around its entire perimeter to ensure excellent air tightness. The blades are operated by a gear mechanism to...
