Filtering plant FOL 2

The FOL 2 filtering plant is intended for use at metalworking plants to clean the air removed from the processing area from oil mist, lubricating and cooling liquids (LCFs) and solid particles. Productivity 2000 m2/h.

The installation is used to clean the air from oil mist and particulate matter, as well as cleans the air from solid particles that are in suspension as a result of metal processing.   The installation has a modular design that provides the possibility of expanding the model range.

The principle of operation of the installation

The first stage of purification: Sedimentation chamber with a screw separator.
Contaminated air, falling on the screw separator, due to the force of gravity allows you to separate solid particles and drops of oil, removing them from the air and depositing them on the walls of the screw separator. Drops of oil, flowing down the separator, fall on an inclined surface and flow into a 2-liter oil container. If the separator gets dirty, it can be easily removed and cleaned.

The second stage of cleaning:
After passing through the screw separator, the air enters a galvanized metal prefilter, where the remaining drops of oil mist are caught. The oil from this filter is also collected in the oil container.

The third stage of cleaning:
A class H14 filter is used for air purification with an efficiency of 99.995% for particles larger than 0.4 microns.

MPPS efficiency 99.995% (EN 1822 @ 1.7 cm / sec) H14

EN 1822

The standard applies to high efficiency and very high efficiency air filters with ultra-low penetration used in the field of ventilation and air conditioning, as well as in technological processes, such as clean room technology or the pharmaceutical industry. It establishes a procedure for determining efficiency based on a method that counts particles using a test liquid aerosol (or, alternatively, a solid) and can classify these filters in a normalized way according to their efficiency.

The principle of operation of the HEPA filter

HEPA filters are formed by a complex fiber system. Fiberglass fibers with a diameter of 0.5 to 2 microns are usually used. The main factors affecting the work are the diameter of the fiber and the thickness of the filter. The air space between the fibers of the HEPA filter is much larger than 0.3 microns.
The notion that the filter acts like a sieve where particles smaller than the largest openings can pass through the filter is not true for HEPA filters. The sieve effect is also true for HEPA filters, but it plays a negative role, leading to premature contamination, reduction of filtration speed and even filter failure. Despite the extreme undesirability of this effect, it is almost impossible to get rid of it.
HEPA filters are designed to filter small particles. These particles are captured by the fibers using the following mechanisms:

The effect of entrapment is manifested if the air current line passes close (at a distance of about the thickness of the fiber or closer) to the filter fiber. The particles stick to the fibers.
The effect of inertia manifests itself for large particles. Due to the large inertia, particles with a large diameter are not able to bypass the fibers, following a curved trajectory in the air flow, and get stuck in one of them. Therefore, they continue to move in a straight line until a direct collision with an obstacle. This effect increases with a decrease in the space between the fibers and an increase in the speed of the air flow.
The effect of diffusion is the collision of the smallest particles of pollution, with a diameter of less than 0.1 μm, with gas particles, followed by the slowing down of the former when passing through the filter. Such particles begin to move away from the air flow lines at a distance exceeding their diameter. This behavior is similar to Brownian motion and increases the probability that the particle will finally stop under the action of one of the above mechanisms. At low air flow speeds, this mechanism becomes dominant.

The diffusion mechanism prevails when filtering particles with diameters less than 0.1 μm. Entrainment and inertia prevail for particles larger than 0.4 μm in diameter. Particles with a size of about 0.2-0.3 microns are not filtered so effectively, they are called Most Penetrating Particle Size (MPPS). The filter class is determined by MPPS.

Control panel

Designed for switching on and off all systems and motors involved in the installation, as well as electrical protection of motors (current, phase shift). The control panel allows you to turn on and turn off the fan according to a given algorithm. The remote control is equipped with a quick connection connector, which allows you to connect the installation without having special education.
