• SS 304 / CRCA powder coated construction except Filters and motor-blower assemblies which will be in standard execution.
• Minipleat HEPA Filter with hot melt technology, which conforms to EU 13 Grade, with an efficiency rating better than 99.99% for 0.3 µ at supply position.
• Intermediate filter which conforms to EU 7 Grade, with efficiency of 95% down to 3 micron. These Filters are basically made from micro-Fibre-glass media and are inherently washable.
• Primary pre filter for suction, which conforms to EU 6 Grade, with efficiency of 95% down to 5 micron. These Filters are basically made from micro-Fibre-glass washable media.
• Motor, Blower provided are statically and dynamically balanced to supply air flow with sufficient capacity and static pressure for entire life of HEPA. Blower is high performance, noise abated and light weighted.
• SS 304 / CRCA powder coated Double Walled Side Panels.
• Magnehelic Differential Pressure Gauge (0 - 25 mm or 0-50 mm) to monitor pressure drop across HEPA Filter.
• Electrical control panel mounted on the side panel of the unit.
• Fluorescent Light (250 Lux)
• ON/OFF Switches for motor & lights
• DOP Test port at upstream of HEPA filter.

• Client to ensure that floor is properly leveled; so that the equipment is installed with covings flush with the floor to avoid any gap.

• Any electrical cabling required between control panel to the supply point is in Client's scope.
• Client to provide facility of 20 psig compressed air / nitrogen cylinder any compressed gas not harmful to personnel for carrying out the HEPA Filter Integrity Test.

• HEPA Filter Integrity Test
• Particle Count Test
• Air Velocity Measurement Test
• Smoke Profile Test (Video Shooting/ Photography to be arranged by client )
