E-PAK 150 DX/300 DX/500 DXEN285 Description5.1 FunctionE-PAK 150 DX/300 DX/500 DX has been designed to filter combustible andnon-combustible dust in a high vacuum system.E-PAK 150 DX/300 DX/500 DX is a complete vacuum unit with a direct-driven side channel fan fitted as one unit on a steel frame and a start andcontrol unit with an integrated 24 V transformer. E-PAK 150 DX is directstarted, while E-PAK 300 DX/500 DX are Y/D started. The unit has automaticstart/stop and automatic filter cleaning in two stages.Filtration in two stagesIn the first stage, the inlet separates course particles. In the second stage, fineparticles are separated on conductive filter bags.Automatic filter cleaningE-PAK 150 DX/300 DX/500 DX uses filter cleaning by a short blast of reversedair flow with atmospheric pressure. By the rapid opening of the filter cleaningvalve located on top of the filter, a powerful blast of reversed air flow iscreated, efficiently dislodging dust from the filter bags.Figure 4 shows the function of E-PAK 150 DX/300 DX/500 DX according tothe following:1. Air flow during normal operation and collection of dust.2. Air with atmospheric pressure released into the filter during filter cleaning.3. Short blast of reversed air flow during filter cleaning.4. Filter cleaning valve.5.2 DimensionsFor the dimensions of E-PAK 150 DX/300 DX/500 DX, see Figure 1, Figure 2and Figure 3.5.3 Technical and electrical data5.3.1 Technical dataTable 5-1: Technical data contains technical data for the E-PAK DX highvacuum units.Figure 27 shows the fan characteristics diagram.
