-- X -- 1. Selection of Model to place an order as Described in literature (AD42XL) ;
i.e. AD ( AD ) = Air Devices
Door width - 4 ft. ( 4 ) = Air Curtain Width Door Height - 2 mt. ( 2 ) = Air Curtain Height(length)
X / Y ( X ) = Single Phase / Three Phase
Flp. ( flp ) = Flame proof motor
90 % of the doors have height below 2.5 mt. so light duty, single phase is used.
If height is above 3 mt., Heavy Duty, Three phase is used.
2. For door width more than 5, multiple Air Curtain (of std. Length) be used.
e.g. For 6 wide door, 2 nos. of 3 long Air Curtain be installed.
For 2 mt. wide door, 2 nos. of 1 mt. long Air Curtain be installed.
3. Basically used to prevent mixing of 2 different atmospheres on 2 sides of a door. So in AC/dust free area, hot, dusty out side air will not enter even if the door is open.
