A HEPA unit only protects anyone if the filter and seals are intact. We challenge each machine with a test aerosol and tag it with the result.
Filters get damaged in transport and gaskets wear out. Regulations and most project specifications require HEPA equipment to be tested before use on an asbestos or mould project and at regular intervals afterwards.
We test on site or at your yard, record each unit by serial number and give you a certificate you can keep with your project file.
Call the office for same-week site visits and rush results, or send the site details and we will reply with a quote.
