Harvest Right Premier Pump Replacement Oil Demister
Oil mist escaping through your vacuum pump doesn’t just create a mess — it signals wasted oil, reduced pump efficiency, and a shorter lifespan for your freeze dryer. The Harvest Right Premier Pump Replacement Oil Demister solves this by intercepting oil-laden exhaust air before it exits the pump, separating the oil from the airstream so only clean air is released. Engineered specifically for the Premier Oil Pump used in Harvest Right Freeze Dryers, the Oil Demister installs directly onto the pump and requires no tools. When it’s time to clean, simply twist it off, rinse it with hot water, let it dry completely, and reattach — keeping maintenance simple and your freeze-drying cycles uninterrupted.

How often should I clean or replace the oil demister?
Cleaning frequency depends on how heavily you use your freeze dryer and the condition of your pump oil. As a general practice, inspect the demister whenever you perform a pump oil change and clean it if you notice visible oil buildup or reduced airflow.
