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.\u003c\/p\u003e\n\u003cp\u003eKey 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.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 99.9972%; height: 215.488px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e670\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e810\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e220\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eWeight (kg)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eVelocity (m³\/h)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e0.29\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003ePressure Drop (Pa)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e94\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e\u003cbr\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"width: 34.846%; height: 19.5898px;\"\u003eLimit Drop Size (µm)\u003c\/td\u003e\n\u003ctd style=\"width: 64.9732%; height: 19.5898px;\"\u003e14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1003\/4488\/9687\/files\/Thermac_Moisture_Filter_Data_Sheet.pdf?v=1780388864\" target=\"_blank\" title=\"Moisture Filter Product Datasheet\" rel=\"noopener\"\u003e\u003cstrong\u003eDownload product datasheet here\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Thermac","offers":[{"title":"2500 NPU","offer_id":53645362528599,"sku":"2096262","price":1000.0,"currency_code":"GBP","in_stock":true},{"title":"5000 NPU","offer_id":53645362561367,"sku":"2096261","price":1200.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/4488\/9687\/files\/New_products-099_d5a2a80d-b960-4ec7-97f6-d617bd17e365.png?v=1779796181"},{"product_id":"air-to-check-pressure-monitor","title":"Air to Check Pressure Monitor","description":"\u003cp\u003eOur Air to check pressure Monitoring system gives real time measurements of the Air Pressure in an Enclosure.\u003c\/p\u003e\n\u003cp\u003eThis information can be accessed remotely to view and download historic data.
