What this sheet is for
Show that the extractor was actually checked and not just switched on, and catch the blocked filter or split hose before the workshop fills with dust.
Who it is for
Woodworkers, turners, ceramic studios, makerspaces and any small workshop with a dust extractor or air filter unit that somebody is responsible for.
How to use it
- Fill in the extractor, filter part number and your own check interval once.
- Tick each item as it is checked, and write what was found in the last column.
- Log every filter and bag replacement with the part number and cost.
- Write your next-due date from the manufacturer's guidance, not from memory.
- Keep the finished sheets — they are the record if anyone asks.
What is on the sheet
2 pages, in this order:
Page 1
Printed under the title: Whether the extractor is actually pulling — the bag or drum emptied, the filter checked, the hoses and seals looked at, one dated line per check, and a separate record of every filter change.
Your interval, your filter grade. How often the filter is checked, what grade it is and whether your workshop has to keep such a record at all depend on your extractor's manual, the dust you make and the rules where you work — check them. This sheet gives you a place to write your own interval and to show the check was done.
Write-on lines: Workshop · Extractor make & model · Serial no. · Filter type & part no. · Bag / drum · Check interval (yours) · Machines it serves
Checks — tick what was done; note anything found
Table, 11 rows: Date · Bag / drum emptied · Filter checked · Filter cleaned · Hoses & seals · Gates & ducting · Suction OK · Done by · Found / action
Page 2
Filter and bag replacements — one line per filter, bag or drum liner fitted
Table, 8 rows: Date · Replaced · Part no. · Supplier · Cost · Next due (yours) · By
Ruled lines: Notes — faults found on the round, ducting changes, machines added or moved
Questions
How often does the filter need checking?
That depends on the extractor, the dust you make and how many hours it runs, and whether you are obliged to keep a record at all depends on the rules where you work. Take the interval from your manual and the rules that apply, write it in the header, and use the sheet to show you kept to it.
Does an ambient air filter unit go on the same sheet?
Yes — use a separate sheet per unit, since each has its own filter, part number and interval.
