Vacuum conveyor for the food industry 141100

Overview
Threaded Line Vac™ by EXAIR is an air operated conveyor that converts ordinary threaded pipe into a powered conveying system for parts, scrap, trim and bulk materials. It installs directly to pipe couplers for easy system assembly. Available sizes range from 3/8 in (10 mm) to 3 in (76 mm) NPT in aluminum, Type 303 stainless steel and Type 316 stainless steel. No moving parts ensures maintenance-free operation.

Applications

• Chip and shaving evacuation
• Part transfer and handling
• Filling operations

Advantages

• Easy attachment to standard pipe and fittings
• No moving parts — minimal maintenance
• Compact and quiet operation
• Available in aluminum and stainless steel grades
• High throughput capability

Materials
Aluminum models are the economical choice for general conveying; maximum temperature rating 250°F (121°C).
Type 303 stainless steel offers good corrosion resistance for food service, abrasive or mildly corrosive environments; maximum temperature rating 800°F (426°C).
Type 316 stainless steel is recommended for critical or sanitary applications requiring superior corrosion resistance; maximum temperature rating 1000°F (538°C).

Models
Threaded Line Vac units are offered individually and in kits. Kits include a Threaded Line Vac, mounting bracket, filter separator and pressure regulator with coupler. Material options: Aluminum, 303 SS, 316 SS, plus high-temperature variants. Size range: 3/8 in to 3 in NPT.

Accessories
Clear PVC hose in a range of I.D. sizes: 3/8 in (10 mm), 1/2 in (13 mm), 3/4 in (19 mm), 1 in (25 mm), 1-1/4 in (32 mm), 1-1/2 in (38 mm), 2 in (51 mm), 2-1/2 in (64 mm), 3 in (76 mm), lengths up to 50 ft (15.2 m). Reinforced heavy-wall hose allows visual confirmation of conveyed material; temperature rating -4 to 150°F (-20 to 66°C).
Mounting brackets available for sizes from 3/8 in (10 mm) through 5 in (127 mm).
Drum covers: fine mesh non-woven covers fit 30 and 55 gallon drums; suitable for hoses 3/4 in through 3.4 in OD; shipped with clamps and strap for installation.

Model comparison

• Aluminum Line Vac — Temp rating: 275°F (135°C) — Corrosion resistance: Fair

• Models 140100 / 141100 / 141100-316 / HT141100 — Air consumption 14.70 SCFM (416 SLPM) — Vacuum approx -42 in H2O (-11 kPa)
• Models 140125–140300 variants — Air consumption up to 68.50 SCFM (1939 SLPM) — Vacuum varies by size

How It Works
Compressed air enters an annular plenum and is injected through directed nozzles. The resulting jets create a vacuum at the intake that draws material into the unit and accelerates it through the conveying line for transport over long vertical or horizontal distances.
