AllergyPlus has introduced Airflex Pro Semi Rigid ducting. Providing a quicker, more hygienic and zero leakage method of residential ductwork installation than traditional methods it helps maintain the energy efficiency savings achieved by specifying Ventilation with Heat Recovery units (MVHR).
A quick and easy to fit system of flexible ducting that can result in up to 70% time saving during the on-site installation process, compared to rigid or spiral duct methods. This innovative system uses low resistance, smooth bore tubing to individually connect each room to the heat recovery unit via an Air Distribution box, and is now recognised as an input to Standard Assessment Procedure (SAP) via Appendix Q.
By directly connecting each inlet/outlet there is zero leakage, so no loss of valuable regained warm air. Also the bore of the duct is coated with anti-static coating ensuring hygienic conditions and easy to clean simply by purging with a high pressure vacuum cleaner.
By direct connection to the air distribution box, noise transmission between rooms is greatly reduced compared to flat duct systems with numerous branches and tee joints. Requiring limited space, Airflex Pro can be fitted in narrow joists due to its high crushability and can be run in concrete screeds for a permanent installation that will never degrade. Available in 75mm diameter (63mm ID) bore size, with a choice of air distribution boxes and termination ceiling adapters.
