Cool Star PRD pressure regulating dampers are designed to maintain a preset constant pressure differential across a partition wall or within a duct system. The damper incorporates a finely balanced aerofoil blade which is capable of regulating room or duct pressures within a tolerance band of ± 3 Pa over a wide air flow range. Control pressures are factory set to customer requirements but may be adjusted in service by changing the blade weights. Typical applications include operating theatres, laboratories, or clean rooms where cascade systems may be used to regulate room pressures. They are also suitable for zone pressurization systems for smoke control in the event of fire.
Passive, balanced blade principle requires no power supply.
Close tolerance control with preset pressures between 15 Pa and 75 Pa.
Wide air handling capacity between 17 lis and 2900 I/s.
Suitable for supply or exhaust applications.
Easy-clean surfaces suitable for medical applications.
May be integrated with external louvres or internal grilles for through the wall installations.
Cool Star make opposed blade volume control dampers for grilles and diffusers has been designed to provide positive control of air. The range is constructed from high quality aluminum alloy extrusions and available for installation on the neck of grilles / diffusers, and also in the duct collars. These dampers are available in matt black finish for long life and non visibility. These d ma pers are key operated from the front face of grilles/ diffusers.
Robust construction for lifelong service.
Smooth gear operation from front face of grilles! diffusers.
Black (matt) for finished non visibility.
Blades are pretensioned with stainless steel spring wire.

The Cool Star range of volume control dampers are particularly suitable for use with air handling units and for air control within ductwork systems where high air velocities and pressures are encountered. The range is constructed with G.I. fully interlocking blades on steel shafts running the length of each blade thus giving the damper exceptional strength. A wide range of control options are available, including manual & electric operators.
Opposed blade operation for optimum air distribution and control.
Operating gear out of ducted airway.
Electric or manual control options.
Large single module units upto 1200x1200mm
Multiple units upto 6000x3000mm.
Welded G.I. frames for rigidity.
The Cool Star range of Fire & Smoke Dampers has been specifically designed to be positioned within the duct system to prevent the free passage of smoke & fire. The range is constructed from heavy gauge galvanized iron sheet having multiple opposed blade construction. The blades are fitted with crome plated spindles operating in self lubricating sintered bronze bushes with stainless steel side seal gaskets to prevent spread of smoke & fire. The operating linkage is fully enclosed.
