Features

Mainly used:

● Central air conditioning and centralized ventilation system pre-filtration

● Large air compressor pre-filtration

● Clean return air system

● Pre-filtration of local high efficiency filtration unit

● High temperature resistant air filter with stainless steel frame and high temperature resistance 250-300 °C filtration efficiency

This first-stage primary filter is commonly used for primary filtration of air conditioning and ventilation systems, as well as for simple air conditioning and ventilation systems that require only one stage of filtration.

G series coarse air filter is divided into eight varieties, namely: G1, G2, G3, G4, GN (nylon mesh filter), GH (metal mesh filter), GC (activated carbon filter), GT (high temperature resistance) Coarse filter).

structure

The outer frame of the filter consists of a sturdy waterproof sheet that holds the folded filter media. The diagonal design of the outer frame provides a large filter area and allows the inner filter to adhere tightly to the outer frame. The perimeter of the filter is bonded to the frame with special professional adhesive glue to prevent air leakage or damage due to windage pressure.

The filter material is placed in a high-strength die-cut cardboard in a folded form with an increased windward area. The dust particles in the inflowing air are effectively blocked by the filter material between the pleats and the pleats. Clean air flows evenly from the other side, so the airflow through the filter is gentle and uniform. Depending on the filter material, the particle size it blocks varies from 0.5μm to 5μm, and the filtration efficiency is different!

Maintenance

1. According to the cleanliness of the environment, regular (primary filter is generally 1~6 months) replacement.

2. Regularly (usually every two months) use the dust particle counter to measure the cleanliness of the cleanliness area cleaned by this product. When the measured cleanliness does not match the required cleanliness, the cause should be identified (whether there is a leak) If the high efficiency filter has failed, replace it with a new high efficiency filter.

3. Stop the initial effect filter when it is replaced.
