Chips, fines & air · review
HEPA filtration and semi-automatic filter cleaning on a shop vacuum — and six and a half horsepower claimed from a domestic socket.
The end of it The right filter and the right cleaning cycle, under a horsepower figure no socket can deliver.
Every figure below names its source. Each one is a manufacturer specification read off the listing itself. The judgments are ours.
The two specifications on this page that matter, and the American half of this shelf has them nowhere else.
A filter loads with fine dust as it works, and that loading — not the tank filling — is what makes suction fade halfway through a sanding job. A cleaning cycle pulses air back through the filter, knocks the cake off, and the airflow recovers.
The published Bosch GAS 35 L SFC+ on the European half of this shelf is bought for precisely that, and its page says so in a line. The published Metabo there has the automatic version.
This is the only machine on this half with either.
About four thousand eight hundred watts.
A 120 volt 15 amp circuit supplies about one thousand eight hundred.
Peak air-watt ratings taken at stall have been the convention in shop vacuum marketing for decades. That does not make them a power output, and the machine draws what the socket gives.
What would describe it is the airflow, in CFM or cubic meters an hour. This page publishes none.
Chips on the floor are a nuisance. The dust that matters is the part that never lands.
Wood dust is classified as a Group 1 carcinogen by the IARC, and the particles that reach the deep lung are below about ten microns — which is to say, invisible in a shaft of sunlight through a workshop window.
So the number that decides what a collector is worth is not its airflow. It is what its filter stops. A machine that moves a great deal of air through a coarse bag is a machine that measures the room’s dust and puts it back.
Ninety-nine point nine five per cent of particles at three tenths of a micron — through the filter.
What it does not describe is the machine around the filter: the seals, the housing joints, the exhaust. A HEPA cartridge in a leaky body is worse than a class M machine with a coarser medium, because the class is measured at the outlet of the whole thing.
The European half of this shelf is judged on that letter. The American half publishes microns and media.
Nothing on either half publishes both.
The only one on this shelf, and not a marketing line.
Fine dust moving down a plastic hose builds a charge, and the charge jumps to whatever is earthed — usually a hand on a machine. It is unpleasant rather than dangerous at this scale, and in a shop with fine airborne dust it is the thing nobody wants a spark near.
The published extraction-fittings shelf in this catalog compares static earthing as one of its criteria. This is the only machine here that addresses it.
Hose, two wands, floor nozzle, universal adapter, crevice nozzle, round brush, three filter bags, a HEPA filter, a utility nozzle, a foam filter.
A listing that enumerates its accessories rather than saying “accessories included” is doing the reader a service, and three listings on this shelf do it.
The foam filter is the wet-pickup one, and with the drain port it is the half of this machine that is a vacuum rather than an extractor.

Not continuously, and not from a domestic socket. Six and a half horsepower is about 4,800 watts; a 120 volt 15 amp circuit supplies about 1,800. Figures like this are peak air-watt ratings taken at stall, and they have been the convention in shop vacuum marketing for decades — which does not make them a power output. The machine draws what the socket gives. What is missing from the page is the number that would actually describe it: the airflow, in CFM or cubic meters an hour, which this listing does not publish at all.
It keeps the suction up. A filter loads with fine dust as it works, and the loading is what makes suction fade halfway through a sanding job — not the tank filling. A cleaning cycle pulses air back through the filter to knock the cake off, so the airflow recovers instead of declining. The published Bosch GAS 35 L SFC+ on the European half of this shelf is bought for exactly this and its page says so in one line; the published Metabo there has the automatic version. This is the only machine on the American half with either.
Two different kinds of claim. HEPA describes the filter medium — conventionally 99.95 per cent of particles at 0.3 microns — and says nothing about whether the machine leaks around the filter, at the seals or out of the exhaust. A dust class is a test of the whole machine: class M allows no more than 0.1 per cent of the dust through, measured at the outlet, and class L one per cent. So a HEPA cartridge in a leaky machine is worse than a class M machine with a coarser medium. Nothing on either half of this shelf publishes both, and this is the only HEPA claim here.
