KU Air Exhaust Valve

Keeping noise and cost levels down to a minimum areprobably the two biggest problems an engineerdesigning a ventilation system has to face today. Thepatented Model KSU Exhaust Valve has been developedwith these criteria in mind and has a very low noise leveleven when the pressure drop across it is large. Thischaracteristic allows relatively high air velocities to beused, permitting the selection of the most economicalsize of ductwork and exhaust valves.

Adjustment of the airflow is simple, the inner conebeing rotated to the required setting and locked inposition with a single nut. Each air valve is suppliedcomplete with a mounting ring from which it can besimply removed for cleaning without affecting the settingof the valve.

ConstructionThe outer body and inner cone are constructed fromsheet steel, stove enamelled white. The outer body isfitted with a gasket to form an airtight seal with themounting ring.

SizesThe Model KSU is manufactured in five sizes, 100, 125,150, 160, 200mm (external diameter of mounting ring).

The Model KU Exhaust Valve is suitable for use with alltypes of ventilating systems and offers an alternative lowcost valve where noise level, although important, is notcritical. Complete with mounting ring.

Adjustment of the airflow is simple, the inner conebeing rotated to the required setting and locked inposition with a single nut. Each air valve is suppliedcomplete with a mounting ring from which it can besimply removed for cleaning without affecting the settingof the valve.

ConstructionThe outer body and inner core are constructed fromsheet steel, stove enamelled white. The outer body isfitted with a gasket to form an airtight seal with themounting ring.

SizesThe Model KU is manufactured in six sizes, 80, 100,125, 150, 160, 200mm (external diameter of mountingring).

DescriptionThe Lindab range of spiral duct grilles have beendesigned for fitting directly to circular ducts without theneed for a special take-off.

For supply grilles the angled hit and miss slidingdamper acts as an air turn as well as a damper.

ConstructionRGS grilles are manufactured from hot galvanized steelplate and are assempbled without welding. This meansthat the grille can be used without further surfacetreatment and the exterior of the grille matches thesurface of the siral duct onto which it is mounted.

Model ReferencesRGS-1 Double deflection grille without damperRGS-7 Double deflection grille with angled hit and

miss damper

FixingBy self tapping screws (provided) through pre-drilledholes in grille frame.

Ordering ProcedureA grille designed for supply air applications must havean angled hit and miss damper (code RGS-7). Pleasegive required length first followed by height and ensurethat an appropriate height has been selected for theduct diameter (see table)
