How to choose stainless steel air filter

When choosing a pre-air filter, remember to check whether it is easy to operate during flushing. Generally, a good pre-air filter is designed to be more user-friendly in this regard. Although the Hanshill pre-filter is automatically backwashed, you only need to turn the knob or wrench when backwashing, which is easy and convenient.

Because iron products are easy to rust, it affects both appearance and health. Therefore, many of our daily necessities are made of stainless steel. Stainless steel filters are more practical than plastic and other materials in terms of service life and health. So how do we choose stainless steel air filters?

Generally, a good pre-air filter can withstand greater water pressure. If the water pressure is unstable, it will damage water pipes, washing machines, water heaters, boilers and other wading equipment, so whether it has enough impact resistance is also one of the key points in choosing a good pre-filter.

There are two types of flushing methods for pre-air filters: direct flushing and backflushing. As far as the current situation is concerned, the technology of backflushing is more advanced. Because the direct flushing type will use tap water containing impurities to flush from top to bottom when flushing, so that impurities are easy to accumulate on the surface of the filter screen, and the recoil technology can recoil with the filtered water from the upper layer, and at the same time perform 360-degree Automatic rotation, so that all angles of the filter can be washed, Hans Hill pre-filter uses the recoil technology.

Whether the filter screen of the pre-filter is good or not also determines its quality. Some pre-filters use nylon filter mesh or stainless steel filter mesh with poor touch (there is no plastic structure for reinforcement inside), so the filter mesh is easy to deform, and it is not very strong and durable. Consumers are advised to purchase air filter materials that are not prone to rust and deformation.
