Our standard LP Airlock features a compact design and is a less expensive alternative to our HD Airlocks. It is a fabricated, flexible tip rotary airlock, designed for mild duty applications. The unit offers the tightest flexible seal to ensure minimal, if any, air leakage. It is used in low-pressure applications, such as on the bottom of a dust collector and for handling dry, free flowing, non-abrasive materials. It minimizes employee exposure to dust and makes the system less susceptible to material back-up and filter damage.
