Standard Features
Materials of Construction
- Main body- 1.2mm, 18 gauge steel with powder- coated finish
- Work table- 1.5mm,16 gauge stainless steel, type 304
- Side walls- UV absorbing toughened glass ( transparent)
HEPA filters for Vertical Down Flow (one) and Exhaust (two in series)
- H 14 as per EN 1822 – 99.997% @ 0.3 micron housed in a negative pressure envelope (shroud) to prevent escape of Contaminated air to atmosphere and work area
Airflow Pattern
- Unidirectional Vertical down flow with 70 % re-circulated and 30 % exhausted with makeup air coming in as Inflow through table front perforations
Average Air Flow Velocities with a uniformity of +/- 20%
- Vertical down flow: 0.3 to 0.45 mps (60 to 90 fpm)
- In flow: 0.45 mps (90 fpm)
- Two independent hot-wire transmitters monitor real time Down flow and Exhaust velocities
Motor Blowers
- Single phase 220-240 V 50 Hz AC induction motors with backward curve impellers separate for Vertical down flow and exhaust air
Control Panel
- Microprocessor based control panel is located at front of the equipment, away from the contaminated air flow path
Work area illumination
- >1200 Lux (>100 foot candles) using fluorescent tube lights located on the front panel away from work zone
UV Light
- Interlocked and programmed to work only when blowers and fluorescent lamps are off and front window is fully closed
Service connections
- 2 gas/vacuum cocks are provided on one side panel with provision for 2 more on the other side panel. 2 ports each are available on side panels for signal cables. Two 5 A female electrical sockets with switches are provided on the unit’s back panel
Mounting Stand, Front Sash and Arm rest
- Powder coated square pipe mounting stand with castor wheels and locking arrangement is provided. Ergonomic design includes angled front sash with counter weights, magnetic switches for door positions, arm rest, eye level LCD displays, alarms etc., for operator comfort
- Each unit is factory tested to meet international guidelines and dispatched in ready-to-plug and play condition with Operating Manual and IQ, OQ, PQ test certificates
Alarms & Safety
- Out of range or incorrect airflow velocity and frontal air barrier velocity
- Incorrect position of front sash-window
- Clogging of HEPA filters
- End of life-cycle of UV LAMP (if fitted)
- Out of range temperature
Governing Standards / Guidelines
- NSF/ANSI 49 -2002 (National Sanitation Foundation, USA)
- EN 12469 -2000 (European Standard)
