Portable Air Cleaning System
can be used as a two- or
three-stage filtration system.
The cleaner is mounted to a
portable cabinet.
Fume extractor arms are perfect for welding booths and other
industrial applications requiring large air capacities. Telescopic
and 7-ft (2.1-m)arms are suitable for small work areas; 10-ft (3.0m) and 14-ft (4.3-m) arms are best for wider work areas. Specially
designed friction joints allow hoods to be positioned at any point
within the work area. Arms are supported by a 360° swivel elbow
for unlimited maneuverability. Maximum operating temperature
is 158°F (70°C). Assembly is required for all models.
The 7-ft (2.1-m), 10-ft (3.0-m), and 14-ft (4.3-m) arms include 10"
x 12" (25.4 x 30.5 cm) oval polycarbonate hood with handle and
damper, and 61/4" (15.9 cm) OD PVC fiberglass-reinforced hose.
Telescopic arms include 14" (35.6 cm) diameter aluminum hood,
and 61/4" (15.9 cm) OD PVC fiberglass-reinforced hose.
Order models with light package for improved work area
illumination. Light package includes halogen lamp, protective grill
(33700-10, -12, and -14 only), and hood-mountable switches for
on/off control of lamp and fan. Lamp operates on 115 VAC, 60 Hz.
A 1/2-hp or 1-hp fan and wall mounting bracket are required to
complete your system­­­—order separately below.
