Static pressure in inches of water, as Grizzly states it. "No pressure given" is Grizzly's air suction capacity, measured at the inlet with no duct attached; it cannot be set against a figure at a stated pressure. Not a ranking.
Matching a collector to the shop
| Work | What suits it | Why, from the documents |
|---|---|---|
| Hand-held sanders and saws, small ports | A shop vacuum or extractor, not a collector | Small hoses and ports; see choosing a shop vacuum |
| One machine at a time, 4 in port, 120 V | A small single-stage or wall-mount collector | G0710: 537 CFM at a 4 in inlet; G0944: 110 V on a 20 A circuit |
| A jointer or planer | A collector whose airflow at your duct's pressure meets the machine maker's figure | Powermatic asks 800 CFM for its 1285 jointer; DEWALT a collector, not a vacuum, for its DW735 planer |
| Several machines on ducting | A cyclone with a published curve or rating at a stated pressure | G0440: measured from 1354 CFM at 2.5 in to 338 CFM at 10.0 in |
| An existing single-stage collector that clogs | A separator rated for it | G0863: for 1.5–3 HP collectors and 750–2300 CFM |
Built from the makers' statements. Not a ranking.
What to compare
- Airflow at a stated pressure. A figure such as 1023 CFM at 1.2 in tells you more than a bare CFM. Better still is a curve or table of airflow across pressures, which Grizzly publishes for the G0440; how to read one is in the dust collector guide.
- The machines' own figures. Grizzly's G0555LX band saw asks for 400 CFM at its port, Powermatic's 1285 jointer for 800 CFM. Compare a collector's airflow at your duct's pressure with each machine maker's figure, one machine at a time, not an average.
- Inlet and adapters. A 6 in inlet with a 4 in adapter, or two or three 4 in inlets, sets how many machines can be connected; Grizzly's cyclones run from 6 in to 8 in inlets.
- Filter. Read each rating in the maker's terms: 30 micron and 2.5 micron bags, 1 micron canisters and cartridges, and one filter rated at 99.97% of 0.3 micron. HEPA, as the EPA defines it, is at least 99.97% of 0.3 micron particles; a micron figure is not a HEPA or MERV rating.
- Supply. The same 1.5 HP class runs on 110 V and a 20 A circuit (G0944, G0860) or needs a 30 A circuit at 110 V for its rated airflow (G0703); the 3 HP cyclones run on 220 V with 30 A circuits. Check the circuit the manual names before choosing, and have any new circuit installed by a qualified electrician.
- Type. A cyclone drops most debris in a drum before the filter; a single-stage machine sends everything through the impeller to its bags or canister, and Grizzly warns any collector against metal or stones, which can strike sparks.
- Noise. Grizzly lists sound ratings without test conditions in the tables reviewed, so they are not compared here.
Safety— Before it runs
Wood dust only, no metal or stones; no open flames or pilot lights in the room; the drum or bag emptied wearing a respirator, away from ignition sources; plastic duct grounded as the collector's manual says. Health and fire risks are set out in the dust collector guide.
Before choosing a dust collector
- Each machine's port and its maker's airflow figure
- Airflow at a stated static pressure, or a curve, for each collector
- Inlet size and number of adapter inlets
- Filter rating in the maker's terms
- Voltage, amps and the circuit size the manual names
- Floor or wall space, and room for emptying the drum or bag
Hand tools and small ports are covered in shop vacuums; fine dust in the room in shop air filters.
Sources
Specification-based: every figure is Grizzly's, from its manuals, in its terms. Airflow given without a static pressure is Grizzly's air suction capacity, measured at the inlet with no duct, and is not comparable with airflow at a stated pressure. Supply figures are listed as stated; wire any machine as its manual says. No collector was tested and none is ranked.
