How to Use the MirOil BD505 Electric Fryer Oil Filter Machine | Step-by-Step Instructions
The MirOil BD505Â is a 55 lb electric fryer oil filter machine designed for commercial fryers with drain valves. It helps restaurants, cafeterias, food trucks, concession stands, churches, schools, and other foodservice operations filter used fryer oil through a MirOil EZ Flow filter bag and pump the filtered oil back into the fryer.
This guide explains the basic BD505 operating process, including how to position the machine, install the filter bag and frame, drain fryer oil into the trolley, pump filtered oil back into the fryer, and clean the machine after use.
For complete safety and operating instructions, always refer to the official MirOil BD505 operator manual.
Proper fryer oil filtration can help remove crumbs, food particles, sediment, and cooking debris from oil. When used as part of a complete MirOil oil care program with MirOil EZ Flow reusable filter bags and MirOil FryPowder oil stabilizer and filter aid, the BD505 can help support cleaner oil, better fried food quality, reduced waste, and lower operating costs.
Step-by-Step BD505 Operating Instructions

1. Check your fryer and oil level
Confirm that your fryer has a drain valve and that the oil volume does not exceed the BD505’s rated 55 lb capacity.

2. Position the BD505 safely
Move the BD505 into place below the fryer drain valve. Make sure the machine is stable, the wheels are locked or controlled, and the drain path is clear.

3. Install the filter bag and frame
Place the correct MirOil EZ Flow filter bag and frame assembly into the BD505 discard trolley before draining oil.

4. Drain oil through the filter bag
Open the fryer drain valve slowly and allow the used fryer oil to flow through the filter bag into the BD505 trolley. The filter bag helps capture crumbs, sediment, and cooking debris.

5. Allow filtration to finish
Wait until the oil has fully passed through the filter bag before pumping oil back into the fryer.

6. Pump filtered oil back into the fryer
Use the BD505 electric pump to return the filtered oil to the fryer.

7. Clean the machine and filter bag
After use, clean the filter bag, frame, trolley, and hose according to the operator manual.
Always follow the official MirOil operator manual and your kitchen’s hot-oil safety procedures. Hot fryer oil can cause serious burns if handled incorrectly.
