OVCD 200 SERIES
Description OPTIMA make high quality single and multi blade Volume Control Dampers are designed for
quiet, efficient and reliable air volume control in ventilation systems.
OVCD-200 Series Volume damper allows even distribution and control of airflow under
conditions of high duct pressures.
The frame is a robust weld assembly of formed channels with flanged connections to ductwork.
The blades are formed single skin reinforced with longitudinal structurally designed ‘3V’or
Aerofoil shape. Special Frame & Blade construction is undertaken for various types of site
applications, light, medium and heavy duty. Blade action is standard as parallel but can be
supplied as opposed action. Blades are fitted with blade tip seals to ensure for minimum air
leakage for a standard construction. For low leakage (less than 1%), as per international
standards DW142 Class, Stainless Steel jamb seals are provided between blade and frame. This is
optional.
All Dampers are silicone sealed and manufactured as per international standards conforming to
NFPA 90 A and UL 181 standards for erosion.
Standard Construction : FRAME: 1.2mm thick (18G) GI sheet steel coating Z-22 to Z-27 as per standard ASTM 653.
Frame is a welded construction, in flange shape, undrilled, Mill finish standard supply.
BLADE: 1.2mm thick (18G) GI sheet steel, single skin blades (3V) form. OR 1.5mm thick GI, double

impregnated bushes are optional.
AXLES: Blades are coupled with Linkage and Frame with Zinc plated spindles, Square or Round.
Spindles are either welded or riveted as per specification.
LINKAGE: 3mm x 12mm zinc plated flat steel linkage for blades operation. Linkage is external on

OVCD 200 SERIES
Volume Control Dampers
Improving your environment
Model: OVCD-220 G-AL-SP
Model: OVCD-220 G-AL-S&C
Description OPTIMA make Non Return Dampers are designed for automatic shut off of individual
sections of the air conditioning system. With the fan in running condition , the degree of
blade opening is a function of air velocity. If the fan is turned off, the blade will close
automatically. In a multi fan installation this prevents back draught through non
operating fan.
OPTIMA make ONRD-200 series models are also called Self Closing Dampers or Gravity
Dampers or Pressure Relief Dampers. The blades are smooth, reliable and designed for
energy saving. These are air operated, opening or closing dampers for intake, discharge
and pressure relief vents in air conditioning systems. Also, designed to maintain a
constant air pressure level inside pressurized rooms.
Construction CASING: The casing is made from high quality AL/GI sheet steel of 18G thickness.
BLADES: Blades are made of 0.3mm/1.00 mm thickness AL/GI steel sheet. Parallel action
blades.
BUSHES: Blades are fitted with nylon bushes for rattle free and smooth operation.
GASKETS: Blades are sealed with foam/rubber gasket at the bottom edge to prevent
rattling noise and facilitate air tight operation.
OPERATION: Frame is fitted with AL/GI stopper to prevent the over movement of blades.
Additional centre partition shall be provided if height or length is more than 900mm.
