EXAIR Back Blow Nozzles

EXAIR has a wide variety of Air Nozzles with all of them meeting or exceeding OSHA Maximum Allowable Noise Exposure OSHA Standard 29 CFR 1910.95 (a) and Dead End Pressure Standard 29 CFR 1910-.242 (b). EXAIR takes pride in engineering products that help improve the safety of your environment.

Our Back blow nozzles are no exception as these nozzles are designed to clean the inside of pipe, tube, hose or channel. The Back Blow Nozzle is designed with a series of holes providing a 360 degree of force of air flow clearing out coolant, chips or debris left behind from your manufacturing process. The nozzle prevents buildup of debris from moving deeper into a pipe or out the other end, causing safety hazard(s). Because debris is moving towards the operator it is recommended that the operator wear personal protective equipment. The Back Blow Nozzles come in 3 sizes for your custom use.

Back Blow Air Nozzle Family

Model 1004SS is the smallest with M4 x 0.5 male thread. It delivers a effective high performance and recommended for diameters ranging from 1/4″ (6.3mm) up to 1″ (25.4mm). This nozzle has a SCFM rating at 4.5 at 80 PSIG and a sound level of 75 dBA.

Model 1006SS has a 1/4″ FNPT thread. It also has an effective high performance with recommended ranges from 7/8″ (22mm) up to 4″ (102mm) diameters. This nozzle has a SCFM rating at 22 at 80 PSIG and a sound level of 80 dBA.

Model 1008SS being the largest with 1FNPT thread. This nozzle is capable of of being used in diameters ranging from 2″ (51 mm) up to 16″ (406mm). This nozzle has a SCFM rating at 80 at 80 PSIG and a sound level of 80 dBA.

These nozzles are specifically designed for clearing debris and will most like need an extension and Chip Shield. EXAIR can help you with your selection, design, quote and order. If you need our help please contact any of our Application Engineers are and eager and ready to help.

EXAIR’s Air Nozzles & Jets: The Engineered Alternative to Cheap or Homemade Blowoffs

If one of your goals is to reduce air consumption in your facility, look no further than EXAIR’s Engineered Air Nozzles & Jets. By upgrading your blowoff, cooling, and drying operations to use one of our Super Air Nozzles or Jets you can save as much as 80% of your compressed air usage when compared with an inefficient solution.

EXAIR’s engineered nozzles are designed to optimize your compressed air system by entraining ambient air along with the supplied air, providing maximum force on the target. Inefficient solutions are commonly used in the form of cheap, plastic nozzles and sometimes even worse, open pipes or tubes. An open copper pipe or tube, even if “flattened” as we’ll commonly see, wastes an excessive amount of compressed air. This wasted compressed air can create problems in the facility due to unnecessarily high energy costs and the pressure drop that can be experienced affecting other processes. In addition to simply using too much compressed air, an open pipe or tube will often produce sound levels in excess of 100 dBA. At these sound levels, according to OSHA, permanent hearing damage will occur in just 2 hours of exposure.

By simply replacing the open tubes/pipe or inefficient solutions with an EXAIR Super Air Nozzle, you can quickly reduce air consumption AND reduce the sound level. Sound level isn’t the only thing an OSHA inspector is going to be concerned about regarding an open pipe blowoff, in addition OSHA 1910.242(b) states that a compressed air nozzle used for blowoff or cleaning purposes cannot be dead-ended when using with pressures in excess of 30 psig. I don’t know if you’ve ever tried to use an air gun with 30 psig fed to it, but the effectiveness of it is dramatically reduced. This is why there needs to be a device installed that’ll prevent it from being dead-ended so that you can operate at a higher pressure.

EXAIR’s Super Air Nozzles are designed with fins that serve two purposes. They help to entrain ambient air from the environment, allowing us to maximize the force and flow from the nozzle but keeping the compressed air consumption minimal. In addition, these fins are what prevents the nozzle openings from being completely blocked off. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual infraction will result in a fine if you’re unfortunate enough to be the victim of an unannounced OSHA inspection.

EXAIR carries a wide range of sizes and materials of nozzles, so you should have no trouble identifying one suitable for your application. Each is in stock and available to ship same day with an order placed by 2:00 ET. If the savings in compressed air alone isn’t enough incentive, some energy providers offer rebate programs for the implementation of an engineered compressed air nozzle. If you need help selecting the best nozzle for your process, give us a call. An Application Engineer is ready and waiting to help analyze your process and recommend the best option.

EXAIR’s Flat Nozzles Can Be Customized for Your Application

EXAIR’s Flat Super Air Nozzles provide a 1” or 2” wide airstream with hard-hitting force. All of EXAIR’s Flat Super Nozzles adhere to OSHA Standard 29 CFR 1910.242(b) for dead-end pressure, providing a safe and efficient method of delivering a strong blast of air.

The flow and force from the Flat Super Air Nozzle is adjustable by regulating the pressure supplied to it as well as by installing different thicknesses of shims. Thicker shims provide more force and flow, while a thinner shim will reduce the force and flow as well as the overall air consumption. This makes the Flat Super Air Nozzle and ideal solution for applications that may require variable force for different applications. Changing out the shim is fast and easy, check out this brief demonstration from one of my colleagues:

The nozzles are also available in your very own Blowoff System that can be customized to fit the exact application. You have the ability to put together the best combination of nozzle, Stay Set Hose, and Magnetic Base to suit your needs. Available with either a single or dual Magnetic Base and any of our Stay Set Hoses, there’s many different possibilities. To begin:

  1. Select the Air Nozzle you’ll need.

EXAMPLE: HP1125SS 2” High Power Stainless Steel Super Air Nozzle

  1. Then select the length of Stay Set Hose. They’re available in lengths ranging from 6”-36”.

EXAMPLE: An HP1125SS with a 24” Stay Set Hose would be an HP1125SS-9224.

  1. Finally, you have the option to also select a Magnetic Base if necessary. These are available with either a one outlet Magnetic Base, or Two Outlet which would include (2) separate nozzles. For a single outlet, change the second digit of the “added on” dash number to a “3”. For a two outlet, change that number to a “4”.

 EXAMPLE: An HP1125SS with 24” Stay Set Hose and Dual Magnetic Base is a Model HP1125SS-9424.

This allows you to customize the solution using ANY nozzle and ANY length Stay Set Hose, creating a custom solution for your application. If you’d like to talk about any of our Super Air Nozzles and which would be best for your application, feel free to give us a call.

EXAIR Super Air Nozzle entrainment

EXAIR’s Super Air Nozzles are designed with fins that serve two purposes. They help to entrain ambient air from the environment, allowing us to maximize the force and flow from the nozzle but keeping the compressed air consumption minimal. In addition, these fins are what prevents the nozzle openings from being completely blocked off. Using an OSHA compliant compressed air nozzle for all points where a blowoff operation is being performed should be a priority. Each individual infraction will result in a fine if you’re subject to an OSHA inspection. Inspections are typically unannounced, so it’s important to take a look around your shop and make sure you’re using approved products.

To ease the installation process, EXAIR manufactures a line of swivel fittings that allow you to position the blowoff precisely. Manufactured in either 303 or 316 stainless steel, the Swivel Fittings allow for movement of 25 degrees from the center axis for a total movement of 50 degrees. With no gaskets or seals to wear out, ther’es no added maintenance required to maintain optimum performance.

Swivels can be used on any of our Air Nozzles up to 1” and can also be used with the Adjustable and Super Air Amplifiers. By simply adding a “W” suffix to the part number, the correctly sized swivel fitting will be added to your order. For example, an 1122W would be one of our 2” Flat Super Air Nozzles with a ¼ NPT male x ¼ NPT female Swivel Fitting included. Stop wasting time trying to find the proper fittings and positioning for your blowoff nozzles! Contact an Application Engineer and get some of EXAIR’s Swivel Fittings and Super Air Nozzles on order today, available from stock.
