Passive House Quality Control
save blushes & time and find leaks before the Pro turns up!
Air is free; uncontrolled air is expensive!
Easy to install
Clear indication of pressure
The dial shows the pressure differential in Pascals. Get to 50 Pa and start looking for the leaks.
Lock & Seal
Find leaks in the air tight layer and repair them at your convienience
As Building Regulations & other stringent standards (e.g. Passive House Standard etc.) makes air leakage testing mandatory, the requirement for all building professionals to have a house significantly air tight in advance of the first fix or final air leakage test is a must.
The Zephair Pre Pro will help the user (builder, window installer, air tightness installer etc.) to under pressurise the building (or part of a building) and whilst this is happening you can walk the rooms and find the remaining weak points in the continuous air tight layer and repair them.
This can be done whilst the rest of the various trades continue to work so disruption to progress will be minimised.
The Zephair Pre Pro can be set up in either an inward or outward opening window or door and clamped in place using its own clamping system with the extra area being sealed with air tight membrane.
The Pre Pro has a dial that shows the pressure difference between the outside and inside of the building and if you can achieve a 50Pa pressure difference with the Pre Pro you can be confident that when the professional tester turns up they too will be able to achieve the pressure threshold required to test to the relevant standard.

So how do you find the leaks?
Feel
Possibly the best way to find leaks is to walk the building feeling your way around the obvious (windows, skirting etc.) using you hands to feel if air is rushing in to replace that being pulled out!
See
Where leaks occur you will often see insulation move or dust swirl. You can also use a smoke pencil/gun too!
Hear
Often with smaller leaks that have an angle on them (window seals, attic hatches etc.) you will get a whistling sound which helps you to locate the problem.
