With safety as a priority during production, all products use top quality components that meet (*ETL relevant as per UL 710 standards.)*Applicable only for DYNAIR model DEV.
Our Total Quality policy is ensured by standard working procedures, with tests and inspections during all production phases.
An e�cient & economical solution to exhaust contaminated air from kitchen hood.They are suitable for conveying kitchen exhaust air, upto a maximum temperature of 80°C.The removal of grease from the exhaust air �ow is a very important part of commercial kitchen operation. If there is no proper grease trap at kitchen hood it could:
1. Increase �re hazard at exhaust duct.2. Increase the frequency of expensive duct cleaning.3. Create bad odor in or near the restaurant surroundings.4. Increase the collection of grease on the roof top which could cause deterioration of roof material (Filter Bank), These problems can be greatly reduced through the use of proper grease trap device at kitchen hood itself.
With our production capability, wide range of �nished products and compo-nents warehouse, we ensure quick delivery to all our customers. Our sta� is trained and dedicated to provide before and after technical plus sales services.

Filtration System AndConstruction
Dirty Air Clean Air
FILTRATION SYSTEM:
A. First stage of �ltration Three stage �ltration systems, which includes:
Stage 3 : Synthetic Bag Filter:1. EN 779 : F92. Arrestance (ASHRAE 52.1) : 99%3. MERV Rating (ASHRAE 52.2) : MERV154. Eurovent : EU9
Stage 2 : Poly�bre Pleated Filter:1. EN 779 : G42. Arrestance (ASHRAE 52.1) : 90-94%3. MERV Rating (ASHRAE 52.2) : MERV84. Eurovent : EU4
Stage 1 : Electrostatic PrecipitatorAir is drawn by the motor/blower through a �lter bank which traps large dust particles. The remaining particles, some as small as 0.01 microns, pass into a strong electrical �eld (ionizing section) where the particulate receives an electrical charge. The charged particles then pass into a collector plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with the same polarity as the particles, which repel, while the interleaving plates are grounded, which attract and collect.
Stage 4 : Bio-Hepa Filter (Optional) 1. EN 779 : H142. Arrestance (ASHRAE 52.1) : 99.995%3. MERV Rating (ASHRAE 52.2) : NA4. Eurovent : EU14
B. Second stage of �ltration S4: Carbon Filter:Durable non-woven polyester base media, impregnated with activated carbon.The unique combination of high quality activated carbon and polyester a�ords odour and particulate trapping e�ciency while maintaining excellent air�ow properties.
FAN SECTION:• DEM series are with DIDW,fan which allows obtaining two
orientations (0° & b 90°) with the same fan.• The key features associated with DEM:
• AMCA certified fan for air and sound • PPGI casing, suitable for outdoor installation • Backward curved impellers are made of cold-rolled sheet steel • Statically & dynamically balanced • Fan & motor assembly mounted on a common base frame and isolated from the main structure by anti vibration mounts and �exible joint on inlet and outlet (optional) • DIDW backward curved type fan (SISW Optional) • Standard accessories with inspection door & drain plug for periodic maintenance • Powder coated impeller, (non-sticky)
CONSTRUCTION:• Filter section: Pentapost design & have strong three way angle
joints of reinforced nylon corners to form a rigid frame structure. Rigid frame work comprises an assembly of externally chamfered extruded aluminium pro�le & nylon corner joints. Inner & outer skin: Standard pre-coated GI sheet, the double skin is to retain the insulation surface clean & to have a smooth surface.
• Asynchronous three-phase motors according to international standards IEC 60034,IEC 60072,EMC2004/108/CE, LVD2006/95/CE, CE marked, IP55, class F, suitable to S1 service (continuous working at constant load).
OPTIONAL FEATURES:• Spray system works by producing a fine atomized mist that is
delivered through strategically placed nozzles in the stack, which actively reduces odour , neutralizing it before it leaves the stack.
• UV filtration - UVC in DEM are another option in odour & grease control, the most e�ective method common today for eliminating unpleasant odours, grease & oil mist from kitchen hood.
• Electrostatic precipitator with wash module
Features & bene�ts Of UV �ltration -
1. Quick and easy snap in installation.2. No noise.3. No pressure drop.4. Easy maintenance.5. High output green lamps contain < 8 mg. of mercury.6. Water tight connections for lamp and wiring.7. Produce no Ozone or other contaminants.
ACCESSORIES:• Control panel (motor starter, status panel for filter bank)• Fire damper• Inlet/outlet flexible connectors• Anti vibration supports• Outlet flange• Inverter speed controllers• Weatherproof canopy• Belt protection
