What are the features of the high-efficiency filters that accompany FFU laminar flow hoods?FFU laminar flow hoods with high-efficiency filters are mainly used in new clean rooms and clean plant renovation, which can improve the cleanliness level, reduce noise and vibration, but also greatly reduce the cost, easy to install and maintain, is the ideal part of the clean environment.FFU laminar flow hood supporting high-efficiency filter features are as follows: 1. FFU laminar flow hood HEPA production commonly used plates are aluminized zipper plate, cold rolled steel plate (A3 plate) and stainless steel plate (SUS201, SUS304, SUS316, etc.), different materials directly affect the FFU high-efficiency filter price one of the costs. The thickness is generally 0.8~1.5mm. (The production of FFU high-efficiency filters belongs to thin plate welding, which requires high welding and polishing techniques for welders. 2. HEPA non-spacer high-efficiency filter mainly adopts heat-soluble adhesive as the separator of the filter element, which is convenient for mechanized production. Coupled with its advantages of small size, lightweight, easy installation, stable efficiency, and uniform air speed, the filters required for large quantities in clean plants now mostly adopt partitionless structures. 3.High efficiency filters without partitions H13:99.97-99.99%@0.3μm与 H14:99.995-99.999%@0.3μm. Different efficiencies and media cost different prices for high-efficiency filters. FFU high-efficiency filters can be modularly connected for use, making FFU high-efficiency filters widely used in clean rooms, clean operating tables, clean production lines, assembled clean rooms, and partial class 100 applications. The FFU high-efficiency filter can be equipped with both primary and high-efficiency filters. The air is drawn in from the top of the FFU and filtered through the primary and high-efficiency filters. The filtered clean air is sent out at a uniform speed of 0.45M/S±20% on the whole outlet side. It provides high-quality clean air for clean rooms and microenvironments of different sizes and cleanliness levels. |
