EASY PLANNING - QUICK INSTALLATION
Airflex PRO
"Semi rigid ducting performance data is now recognised by the UK Government as an input for Standard Assessment Procedure (SAP) calculations via Appendix Q"
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.
NEW IN 2011
BRE have introduced "Specification requirements applicable to the utilisation of Rigid Duct performance data for dwellings fitted with Semi-Rigid duct within the Standard Assessment Procedure (SAP) via Appendix Q" (www.sap-apprendixq.org.uk)
INSTALLATION:
- Save up to 70% on ducting installation time
- Flexible and compact, suits narrow joists and screeded floors
- Compatible with traditional, i joist and metal web joist systems
- Quick and easy assembly with push fittings
- Taping or sealing with non-hardening sealant is not required
- Compatible with Airflex ISO insulated ducting and air distribution boxes.
PERFORMANCE:
- Zero leakage ensures performance - no loss of valuable regained air
- High crushability (S = 16 kN/m2) withstands external pressure to EN ISO9969
- Low resistance pipe compared to flexible ducting with relatively constant volume
- Superior flow characteristics, High efficiency by connecting each room individually
- Very low noise transmission between rooms
- Recognised as an input to Standard Assessment Procedure (SAP) via Appendix Q.
HYGIENE:
- Smooth 75mm diameter bore for easy cleaning
- Anti-static coating prevents dust build up reducing dust traps
- Corrosion and abrasion resistant to avoid scale build up
- No evaporation of harmful substances - toxically safe
- Easily accessible from extract terminals and distribution boxes - easy to inspect and blow through with a commercial vacuum cleaner
SYSTEM:
- Zero leakage system satisfies compliance and offers reduced labour costs to install
- Cost effective with low maintenance and long life
- Offers freedom of design with choice of different components to suit any layout
- Flexibility of the system allows for majority of ducting to sit inside loft insulation - reducing the cost of insulating the ducting
