Moisture Filter for Negative Pressure Unit
Thermac's NPU Moisture Filter has been designed to help protect both the primary filter and the HEPA-14 filter within a Negative Pressure Unit (NPU), when used within wet blasting environments in the asbestos industry. The Moisture Filter prolongs the life of the NPU by preventing moisture entering the pre-filter and the unit itself. This protects the integral workings of the NPU and delivers cost-savings by reducing the number of pre-filters required when operating an NPU in a wet environment. It also prevents premature damage to the HEPA-14 filter.
Key Features: The NPU Moisture Filter consists of two sections. The first incorporates Thermac's unique filter technology which separates the water vapour from the air being drawn through the Negative Pressure Unit. This prolongs the life of the pre-filter and ensures the NPU runs at maximum efficiency in a moisture-rich environment. The second section houses the pre-filters, the first is a Type 90 Glass Fibre filter and the second a G4 Pre-Filter. This features an easy access opening so that the pre-filters can be replaced as and when required. The Moisture Filter also comes with a 17-litre removable drip tray with carry handles, to facilitate disposal of the collected water. A blanking plate is also supplied to protect the filter face when in transit. The Moisture Filter is securely attached to the front of the NPU with the integrated magnetic fixing system.
