Filtering units

Filtering unit UFO-4-M

Application

The UFO-4-M filtering unit is designed for cleaning the dust laden air from contamination arising during manufacturing processes. It is irreplaceable in capturing the dry dust (without caustic pollutants, flammable compounds or of explosive properties) emitted during welding, grinding of the non-sparking materials, gas- or plasma metal cutting or other processes in chemical industry, food industry, pharmaceutical and plastics industry etc. The maximum temperature of the forwarded air is 140 F.

Filtering unit UFO-4-M

Structure

The UFO-4-M filtering unit consists of filtering modules placed vertically one on top of another and the fan-chamber. The lower filtering chamber is installed on a square base-frame with a chute and a waste-container.

  • UFO-4-M-1 consist of one filtering module and a fan-chamber
  • UFO-4-M-2 consist of two filtering modules and a fan-chamber
  • UFO-4-M-3 consist of three filtering modules

Each filtering chamber is divided with a partition into two parts:

  • Chamber of filters – containing 4 cartridge filters
  • Chamber of electro-valves: there is installed a compressed-air tank (supplied from the compressed-air installation of 6 bar), and 4 electro-valves for filter regeneration (by means of the impulses of compressed-air). The filter regeneration is proceeding automatically.

The UFO-4-M filtering unit is equipped with 2 connection ferrules: inlet ferrule and outlet ferrule in each filtering chamber. The inlet ferrule is placed in the side-wall and the outlet ferrule is placed in the upper-surface of the chamber. In the standard execution the inlet ferrule is placed on the right side of the device (when viewing at the inspection door). It is also possible to replace the side-walls in such a way that the inlet ferrule is on the left side of the device.

The fan-chamber (isolated acoustically) contains the radial fan with a motor and it is installed on top of the most upper filtering chamber as a separate module. Together with the device is delivered a control unit as a power supply for the fan and as a control item for the pneumatic filter regeneration system. The control unit is fixed on the left side-wall of the device. The additional equipment (delivered on separate order) is separator – type SEP – adapted by size to the filtering unit.
