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.
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.
The EXAIR Flat Super Air Nozzles are manufactured to blow a wide forceful stream of air. Their patented design creates a high velocity, laminar air stream with minimal air consumption and low noise. They come in two widths; 1” (25mm) and 2” (51mm). EXAIR offers a standard Flat Super Air Nozzle and a High Force Flat Super Air Nozzle in two different materials, zinc-aluminum alloy and 316 stainless steel. And with a metal construction, breakage is not a concern and performance are not sacrificed even in the harshest of environments.
The unique patented shims inside the EXAIR Flat Super Air Nozzles will give you three improvements to the design and function. First, they come in different thickness to create a wide range of forces. In conjunction with a regulator, you can “dial” in the correct amount of force from a breeze to a blast without overusing your air compressor. The patented design also allows an even flow across the entire width of the air nozzle. Lastly, they help to entrain the free ambient air; so that less compressed air is required. The high efficiency design will save you money. The EXAIR Flat Super Air Nozzles are effective in uniform blowing with safety and efficiency in mind.
To expand more on force adjustments with the Flat Super Air Nozzles, EXAIR has an easy way to change the shim to better suit your application. You can increase or decrease the force of the nozzle by just removing two screws and changing the thickness of the shim inside. EXAIR offers a variety pack called a Shim Set to give you a wide range of forces with the nozzles. For the standard Flat Super Air Nozzle, they come stock with a 0.015” (0.38mm) shim for both the 1” and 2” sizes. The corresponding Shim Sets will include a 0.005” (0.13mm), 0.010” (0.25mm), and 0.020” (0.51mm) shim. The High Force Flat Super Air Nozzles will come standard with a 0.025” (0.64mm) shim; and the Shim Set will include a 0.020” (0.51mm) and 0.030” (0.76mm) thick shim. This is a unique feature as most competitive flat nozzles do not allow you to do this. The chart below corresponds the appropriate Shim Set to the Flat Super Air Nozzle.
Not only are they safe, and easily adjustable they can help save compressed air vs using a open ended pipe!
For example, let’s look at the average operating costs for a single 1/4″ open copper tube. (If you don’t know you current energy costs, a reasonable average to use is $ 0.25 per every 1,000 SCF used, based on $ 0.08/kWh.
A single 1/4″ open copper tube consumes 33 SCFM @ 80 PSIG and costs roughly $ 0.50 per hour to operate. (33 SCF x 60 minutes x $ 0.25 / 1,000 = $ 0.50). For an 8 hour shift, the total cost would be $ 4.00 ($ 0.50 x 8 hours = $ 4.00).
If we were to replace the 1/4″ open copper tube with our Model # 1122 2″ Flat Super Air Nozzle with 1/4″ FNPT inlet, the air consumption would be reduced to 21.8 SCFM @ 80 PSIG. This may not seem like much of an air usage reduction, but when you look at the monetary, total cost of ownership for purchasing and operating the nozzle, the savings can quickly add up.
The operating cost for a 2″ Flat Super Air Nozzle with 1/4″ FNPT inlet is $ 0.33 per hour (21.8 SCF x 60 minutes x $ 0.25 / 1,000 = $ .033) or $ 2.64 per 8 hour shift ($ 0.33 x 8 hours = $ 2.64).
We can now compare the operational cost between the 2 devices:
1/4″ open copper tube operating costs: $ 0.50 per hour $ 4.00 per day (8 hours)
2″ Flat Super Air Nozzle operating costs: $ 0.33 per hour $ 2.64 per day (8 hours)
Cost Savings: $ 4.00 / day (open copper tube) – $ 2.64 / day (2″ Flat Super Air Nozzle) = $ 1.36 savings per day
The Model # 1122 2″ Flat Super Air Nozzle has a list price $ 67.00 USD.
ROI or Return On Investment calculation: $ 67.00 (Cost) / $ 1.36 (savings per day) = 49.26 days.
The 2″ Flat Super Air Nozzle would pay for itself in just over 49 days in operation. This is the savings for replacing just ONE 1/4″ open copper tube with an engineered solution! In most industrial plants, there could be several of these which presents even more opportunities to reduce the overall operational costs.
Our focus here at EXAIR is to improve the overall efficiency of industrial compressed air operating processes and point of use compressed air operated products. If you are looking to reduce compressed air usage in your facility, contact an application engineer and let us help you optimize your current system.
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 EXAIRSuper 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 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:
Select the Air Nozzle you’ll need.
EXAMPLE: HP1125SS 2” High Power Stainless Steel Super Air Nozzle
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.
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.
