Spiral Access Doors

Our spiral duct access doors are designed to grant access for regular duct cleaning, as well as hygiene, maintenance and inspections. They can also enable access to fire and volume control dampers and associated ventilation and air conditioning equipment mounted inside the ducting.

The materials they are manufactured from are resistant to corrosion, have a polyamide locking knob, and zinc-plated mild steel bolts. On each product, you will find a datasheet with installation instructions, turning our access doors for round ducts into easy-to-use solutions. 

We provide a range of different sizes for our access doors in order to fit circular/spiral ducting from 100mm to 1,000mm. When properly installed, they can withstand positive or negative pressures of up to 5000 Pa.These doors are fitted with a gasket & are considered splash tight. Our spiral duct access doors can be installed indoors or outdoors.

Our access doors are pressed from galvanised steel in a sturdy double-shell design with a flow-optimised inner shell to prevent turbulence.

Two knobs are used in order to fix the access panels to the duct. Each access door includes a self-adhesive drilling plate.
