Sanitary Flange Air Operated Conveyors – The EXAIR Line Vac

The ability to control the flow of materials has been a staple in human civilization since 4000 BCE. This includes the creation of pipes which have appeared as early as 2400 BCE from the Egyptians. These piping systems have since then been improved on to be made stronger, lighter, cheaper,  of various styles, and in a variety of materials. One of these styles is the sanitary flange pipe.

Sanitary flange pipe and fittings is one of the larger milestones in piping innovation. Sanitary flange pipes came about due the stringent cleanliness controls in certain industries such as food and pharmaceutical. Both of these use a highly corrosive and caustic soap to sanitize surfaces and, in most cases, entire rooms. Sanitary flange pipes allow for pipe systems to be taken apart easily so that components can be easily cleaned out on a regular sterilization process, and are generally made of 316 Stainless Steel to withstand the corrosive nature of the cleaning compound.

Type 316 Stainless Steel Line Vac

EXAIR Line Vac Air Operated Conveyors have always been well suited for these applications since the internal components are smooth and can be cleaned out easily and sanitized. They have also been made out of 316 Stainless Steel for years which provides superior corrosion resistance and can withstand most caustic cleaners and oxidants. Type-316 Stainless Steel is the preferred material for many food and pharmaceutical applications. Before EXAIR’s Sanitary Flange Line Vac, we noticed our customers would use the standard smooth Line Vac and weld a sanitary flange onto the ends, or installing adaptors on our Threaded Line Vac.

With that thought we decided to make things easier and developed the Sanitary Line Vac which follows the basic design of the Standard Line Vac and operates with the same performance characteristics. Sanitary Flange Line Vacs come in four sizes: 1-1/2”, 2”, 2-1/2”, and 3”. These sizes are the most common sizes for Line Vacs and covers the majority of application needs.

Air Operated Conveyors for a Multitude of Jobs

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. Most applications can be completed using one of our many stock Line Vacs. Additional applications include part transfer, waste or trim removal, hopper loading, filling operations, chip removal and fiber tensioning.

line vac family
Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

They are available from 3/8″ to 5″ diameters, for use with hose, tube or pipe. Line VAcs have smooth ends for hose or tube. The threaded models use NPT threads from 3/8 NPT to 3 NPT to turn ordinary pipe into an air conveyor! They can also be bought with sanitary flange ends for easy disassembly when necessary for cleaning or maintenance.

Materials include aluminum, Type 303 and Type 316 stainless steel or a hardened steel alloy for moving abrasive materials like garnet, glass, or blasting media.

With that being said, there are always applications that need a special product. And because of that we do make “special” or custom products when the need arises.

Special PVDF Line Vac

For example this Live Vac has the sanitary flange design, but the customer needed it made from a special material so their product passing through it wouldn’t be contaminated by metal. So we did just that, we designed built and shipped this line vac and it worked amazingly well!

Accessories include the transport hose, mounting brackets, filter and regulators.  A filtering drum cover is very useful to keep material and/or dust inside, when transporting materials into a drum.

No matter what kind of bulk material you need to move, or what type of special conditions you have. EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

EXAIR Line Vacs: Dozens Of Models; Endless Applications

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate.  Consider this list of uses, starting with our smallest Line Vac, and going to our largest:

  • Model 6058 3/8″ Stainless Steel Line Vacs pull mica from a bulk container and spray it into a mold for making decorative stones, to apply a glittery surface.  They used to do it by hand, but the Line Vacs spread it more consistently.
  • A Model 6079 1/2″ Aluminum Line Vac pulls small metal scraps from a metal trimming operation, as they’re cut, keeping the work area clean.
  • Model 130075 3/4″ Light Duty Line Vacs perform a similar function in a plastic cutting machine, conveying away cut chips and eliminating the need for periodically stopping the machine to clean up.
  • A medical device manufacturer saw a 50% increase in productivity when they went from removing flash by hand from molded silicon parts to using a Model 6061 1″ Stainless Steel Line Vac to suction it away automatically.
  • A mining equipment manufacturer reclaims sand from a secondary operation on their green sand molds with a Model 6062 1-1/4″ Stainless Steel Line Vac.  This keeps their mold area clean, and has eliminated waste in production.
  • Model 140125 1-1/4 MNPT Aluminum Threaded Line Vacs eliminated a  “bucket and ladder” operation where cotton seeds needed to be loaded into 7-foot high hoppers.
  • Model 151150 1-1/2 MNPT Heavy Duty Threaded Line Vacs, fitted into black iron pipe systems, reclaim hot metal chips from a deep channel milling machine, automating the transfer to the recycling hopper.  This eliminated the risk of lifting AND burn injuries from the manual handling of the hot chips.
  • Model 6084 2″ Aluminum Line Vacs vacuum trim scrap from custom label making machines to a central scrap bin, keeping the floor clean, and keeping operators from having to empty individual bins at each machine.
  • A Model 6065 2-1/2″ Stainless Steel Line Vac conveys rejected peanuts (identified and segregated by a vision sorting machine) from the catch pan to a large collection hopper.  This is hauled away at the end of each shift, instead of an operator paying constant attention to the catch pan.
  • Model 161300-316 3″ Sanitary Flange Line Vacs replaced mechanical conveyors in a grain mill, incorporating a totally enclosed Clean In Place (CIP) system.  This greatly reduced contamination controls when the product was openly conveyed, and actually increased their conveyance rates of their bulk grains.
  • A Model 6087 4″ Aluminum Line Vac conveys an additive (in pellet form) into an asphalt mixer, replacing an auger conveyor that left product in the hopper and would clog regularly, resulting in messy spills.
  • A company that recycles spent ammo from gun ranges uses a Model 6088 5″ Aluminum Line Vac to convey the granulated rubber backstop material into their truck.  After the ammo is separated, they use the Line Vac to replenish the granulated rubber into the backstop.
  • A Model 130600 6″ Light Duty Line Vac conveys linen squares (mostly 12″ and 24″ square) through the main header of a sorting operation in a commercial laundry facility.  The system also incorporates several Model 120024 4″ Super Air Amplifiers in individual “pickup” branches.

The EXAIR Line Vac is a fast, low cost way to convey most any bulk material.

No matter what kind of bulk material you need to move, EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

EXAIR Line Vac, Air Operated Conveyors, Expand to Include Sanitary Flange Models

EXAIR’s Air Operated Conveyor product line just expanded, making it easier than ever for a wide range of industries to solve an ever growing range of bulk conveyance applications. Before we get to that, let’s look at just how versatile the Line Vacs are:

The standard Line Vac has been making bulk conveyance as easy as it could get for years now. They come in sizes from 3/8″ to 5″, and all you need is a hose to move material from point A to point B.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

When rigid pipe is preferable to hose, our Threaded Line Vacs offer the same performance:

These come with male NPT threads from 3/8″ to 3″. They’re also available in aluminum, 303SS and 316SS, and High Temperature versions, same as the standard Line Vac.

If you need high power for higher conveyance rates, longer distances, or very dense material, the Heavy Duty Line Vacs are what you’re looking for.

They come in sizes from 3/4″ to 3″, with options for slip-on hose or threaded pipe. They’re also made of a hardened alloy for superior abrasion resistance.

Light Duty Line Vacs are aimed at applications implied by the name…when smaller volumes of low density material don’t require all the head & flow generated by the standard or Heavy Duty models, these are as quick & convenient as the rest, and come in sizes from 3/4″ to 6″.

They’re also ideal when fragile parts might be subject to damage in the high velocity, turbulent air flow produced by the other models.

The newest additions to the Line Vac family are the Type 316 Stainless Steel Sanitary Flange models:

Also known as Tri-Clamp or Tri Clover, these connectors have a variety of advantages beneficial to certain industries: Quick to make up & take apart. No nooks or crevices, so they’re easy to clean. Wide variety of fittings, pipe and tubing are readily available.

These are especially popular in pharmaceutical, food, and brewing applications.
