The duct cleanliness vacuum test pump comes with a protective waterproof plastic carry case, flow meter, shoulder strap, battery charger, magnetic template and small screwdriver. If required we can provide the pump with customised logos attached (at additional cost). The 10 x 10cm magnetic template for PVT testing is supplied in accordance with TR19 and BSEN15780, this is flexible to allow ease of use in circular ductwork. The shoulder strap allows for easy operation if working from a ladder and makes carrying the pump quick and simple. The test pump runs on lithium-Ion batteries which deliver consistent power, meaning the pump’s performance does not fade as the battery’s charge decreases.
The preferred vacuum test method is advised in BS EN 15780, as well as TR19, as the most suitable method for post clean verification of HVAC systems. The pump is used to perform preferred vacuum test (PVT) sampling with a vacuum test capsule. The capsule is then sent in to our independent laboratory for weighing and analysis. Capsules are sold separately to the vacuum test pump. PVT sampling is also used for HVAC system inspection to assess whether cleaning is required. All capsules should be sent off to our laboratory along with an analysis request form which will include all of the relevant project details for the laboratory.
