Accessories

G9955—Bench Top Dual Fan Dust Filter

Two separately switched fan motors can be used

to draw a maximum 400 CFM of your dusty shop

air though the 5 micron pleated filter. Perfect for

sanding and power carving, the clear plastic hood

helps to direct flow from the work area directly into

the filter.

Figure 10. G9955 Dust Filter.

Figure 9. Half-mask respirator and disposable

cartridge filters.

H2499—Small Half-Mask Respirator

H3631—Medium Half-Mask Respirator

H3632—Large Half-Mask Respirator

H3635—Disposable Cartridge Filter Pair P100

Wood dust is a known carcinogen and has been

linked to nasal cancer and severe respiratory ill-

nesses. If you work around dust everyday, a half-

mask respirator can be a lifesaver. Also compat-

ible with safety glasses!

H3275—1⁄4" x 25' Coil Hose

These recoil hoses stay neatly coiled when not

in use, yet stretch to full length when needed.

Great for bench-top use when clutter is always a

concern. Coil springs protect ends from kinking.
