How is a floor plenum air test carried out?


How is a floor plenum air test carried out?

In brief, we remove a box a temporary a tile is removed from the plenum and our fan housing is installed directly above the opening. A fan is then installed into the box and this is all sealed against the floor. Any air handling ducts serving the test zone need to be turned off, isolated and temporarily sealed, stopping the passage of air to outside of the test zone via duct-work. Thereafter another tile is removed and a mock floor tile with a drill hole for the high pressure tube is installed in its place. After the equipment is set up a series of tests is undertake and the readings recorded and then checked against the floor plenum air tightness specification.



If the plenum test fails, you’re APT plenum test engineer will carry out a smoke test to look for air leakage paths. If you have floor or ceiling plenums in your building you need to be aware that a staggering 70-80% fail their first air tightness test. APT Sound Testing has years of experience of raised access floor plenum testing and can work with you to ensure you pass your floor plenum air test at the first attempt.

We can ensure that an onsite air test site audit is arranged as soon as the floor is in place; we can then undertake an initial floor plenum air test and smoke survey to check the air leakage result and check for air leakage paths within the plenum envelope. Once we have assessed the air leakage paths we can then supply a smoke survey report for your sealing contractors to use as reference to ensure your plenums are adequately sealed.



If you would like more information in regards to the most common air leakage paths visit our Plenum Testing page or call us on 01525 303905. Supporting document BG65 / 2016 also contains lots of information on how to design, constructing and test floor plenums.

Constructing Floor Plenums to Pass Air Tightness Testing

Constructing Floor Plenums to Pass Air Tightness Testing  There are many considerations when designing and constructing floor plenums to pass the air tightness testing .  In offices, carpet tiles are usually laid over the raised access floor, if joints between carpet tiles are not lined up with the joints between the raised access panel’s floor tiles or panels, the air leakage will be reduced, particularly if the carpet tiles are glued in place. That said, the laying of carpet tiles should not be relied on to achieve the target for the raised access floor itself as these can debond over time resulting in multiple air leakage paths throughout the raised access floor. Many raised access floors include electrical and date boxes. The air leakage of these boxes should be ascertained, to ensure that they will not significantly contribute to the raised access floor leakage, and reduce the air flow to the grills or diffusers. Where there are decorative or functional connect...

The Most Common Air Leakage Paths in Floor Plenums

Image
The most common air leakage paths in floor plenums In order to create an effective airtight floor plenum and achieve a successful floor plenum air test, all mechanical and electrical penetrations and perimeter joints must be properly sealed. An evaluation of the following areas/components that can typically create Inefficiencies should be undertaken during the early design phases: 1. All service penetrations through the access floor, walls and sub-floor including:    a. Cable bundles and cable trays    b. Pipes    c. Fire/plenum barriers 2. Cable trunking – must be internally sealed within the void 3. Masonry work - incomplete or poorly jointed masonry walls will result in greater air leakage. All masonry joints must be filled and masonry paint applied as a finish. 4. Risers need to be properly sealed throughout all plenums/ducting need to be sealed. 5. Plasterboard on studs at board edges and the ends below the raised floor...

The main terms used in the construction of floor plenums

Image
The main terms used in the construction of floor plenums We often get asked many questions regarding the construction of floor plenums.   To try and help our customers we have offered an explanation of the main terms used in floor plenums. Floor Panel – the load bearing, horizontal component of a Raised Access Floor system Floor Pedestal – the vertical, adjustable supporting component of a Raised Access Floor system Subfloor – the existing floor upon which a raised Access Floor System is installed. Plenum wall – the new and/or existing walls to the plenum, that compartments the plenum from the surrounding the other plenum zones. Finished Floor Height – the finished floor height from the subfloor, void height and panel thickness combined. Plenum Void – the space between the underside of a raised floor and the existing sub floor, sometimes referred to as a cavity or plenum. Service penetrations – these are usually ducts or cable trays that penetrate the plenum envel...
