DraftMax Advance Spare Parts FAQs
Straight answers to the questions people ask most when looking for spare parts for a downdraft extraction table.
How do I identify the right spare part for my downdraft table?
Start with the data plate on the table, which gives the model, serial number, electrical details and often the date of manufacture. Note these, along with the part number on the old part and anything printed on it.
Tables have been made in several versions over the years, with differences in controls, fan and electrical parts, so parts that look alike can differ. Have the manual to hand. If you are unsure, our team can help you identify the part.
Which parts wear or fail most often?
Electrical parts such as switches, push buttons, relays, fuses and overload relays are the usual faults, along with filter cleaning parts such as pressure valves and membranes, and the fan or motor over a long life. Adjustable feet and fittings can be damaged by use.
Regular checks of controls, indicators and airflow help you spot a failing part early.
Why is extraction weak?
The commonest cause is a blocked or full filter. Others include a fan running backwards on a three-phase table, a worn or damaged fan wheel, leaks in the ducting or door seals, and a cleaning system that has stopped working.
Check the filter condition and the indicator first. If the fan wheel is damaged or loose, stop using the table until it is repaired.
How does the filter cleaning system work and what can go wrong?
Many extraction tables clean their filters with pulses of compressed air, controlled by valves, a pressure regulator and a control board. If the pressure is wrong, a valve or diaphragm has failed, or the control board is faulty, the filters clog and extraction drops.
The air supply should be clean and dry, and the pressure set as the maker directs. Check the data plate and manual for your own table to see what cleaning system it has and what pressure it needs. Do not alter or bypass any safety device fitted to the air system.
