Description
The IAD range of duct access doors is designed to provide easy and speedy access to smoke, fire and volumecontrol dampers, coils, filters and other air conditioning and ventilation equipment mounted inside ductwork.
The range of five sizes have been carefully selected to provide different degrees of access from single handed to head and shoulder entry.
IAD access doors are of double skin “sandwich” construction complete with 20mm thick high density insulation and are sealed to prevent any insulation migration.
The one piece mounting frames are pressed for accuracy and prepunched on inner and outer flanges.
This feature allows doors to be installed so that a flush finish is achieved on plain or
insulated ductwork.
All sizes of door are fitted, as standard, with a retaining chain between the door and frame.
IAD access doors are suitable for high, medium and low pressure applications and meet the requirements of HVCA DW144 Specification classes A and B
