3M 33786 Vacuumer 30L

The 3M 33786 is a 30-litre workshop vacuum built for bodyshops and paint facilities that sand daily. Its 1,450 litre-per-minute airflow pulls dust directly off the sanding disc before fine particles can settle on fresh paint. The automatic filter cleaning sends periodic air pulses back through the filter to maintain constant suction, so you never have to stop and clean it manually. Class M filtration ensures that fine sanding dust is safely captured. Robust wheels, a drop-down filter access door and a 69 dB noise level make it a practical choice for long shifts on the workshop floor.

What's inside

3M 33786 Vacuumer 30L dust extractor with Class M filter and automatic filter cleaning system

Why this product

• 1,450 l/min airflow for immediate dust removal at the sanding disc, preventing particles from settling on fresh paint

• Automatic filter cleaning: sustained suction throughout the session without manual stoppages or filter checks

• Class M filtration captures the fine particles generated by sanding paint, primer and filler

• 69 dB noise level: among the quietest extractors available in the 30-litre capacity class

• Compatible with pneumatic and electric sanders via standard 27 or 35 mm coupling

How to use

1. Connect the extraction hose to your sander (Use a standard 27 or 35 mm coupling to attach the 33786 hose to the dust port of your random orbital sander.)

2. Switch on the vacuum before starting the sander (Always start the 33786 first so suction is active from the first movement of the disc. This captures dust from the very beginning of your pass.)

3. Sand and let the automatic filter cleaning run (The vacuum cleans its own filter during use. Check the collection bin periodically and empty it when it reaches three-quarters full.)

4. Inspect the filter via the drop-down door after each session (Open the side door, remove any remaining dust cakes and check the filter for damage. A clean filter maintains peak suction performance.)

Pair with 3M Perfect-It III Machine Polish, Commandant Rubbing Compound M3, a tack cloth for dust pick-up and the Liquid Elements T4200 orbital polisher for a complete paint correction workflow.
