We are offering here the Pre Filter that removes unwanted large paticles from air and water. Supplied air in the workplace or transport vehicles has air pre-filters to remove dust, hair, insects, pollen, fibers, etc.. Water pre-filters remove sand, fibers and larger pollutants of drinking water. The filter protects the amin filter from clogging with debris. They are the first step in the air purificaion process. The filter is made for use in the industrial applications. The offered Pre filter  is located upstream of the main filter, so airflow will go through the pre-filter before it touches the main filter.
