Harvest Right Oil Filter

Quick, Easy Oil Filtration
Keep your vacuum pump running smoothly and extend its life with the Harvest Right Oil Filter. Designed specifically for vacuum pump oil, this filter makes it simple to remove water and particulates, helping your freeze dryer maintain top performance.

What’s Included

• 1 × Oil Filter Unit

• Built-in lid dial (optional reminder to track last filtration month)

Benefits

• Simple filtration process extends pump life

• Improves freeze dryer efficiency and performance

• Separates water and debris from pump oil

• Designed exclusively for vacuum pump oil (not dishwasher safe)

Directions for Use

First Use:

1. Remove cartridge packaging.

2. Place the cartridge into the filter holder and press firmly until sealed.

Oil Filtration Steps:

1. Open the vacuum pump drain valve and allow oil to drain into the filter (tilt pump if needed).

2. Wait for oil to fully pass through the filtration system.

3. Water will naturally separate and sink to the bottom; clean oil floats on top.

4. Carefully pour off the oil and discard the water. Never pour water back into the pump.

5. Refill the pump with filtered or new oil.

Maintenance & Replacement

How to know your oil is clean:

• Oil is clear of debris/particles

• Not milky or chalky

• Clarity is visible (yellow/amber color is acceptable)

• Pump achieves suitable vacuum pressure (mTorr)

When to replace your filter or cartridge:

• Oil no longer drains through filter (clogged)

• Filtered oil still appears milky or dirty

• After ~15–20 uses, or sooner depending on oil quality

Replacement cartridges are available directly from Harvest Right.

⚠️ Important: This filter is not dishwasher safe and should be used only for vacuum pump oil.
