What types of Air knives do we carry?
The Regular Air Knife is a good choice when a less expensive alternative is required. It is louder and uses more compressed air than the Advanced Air Knife.
The Advanced Air Knife is normally the best choice due to very low noise levels and it uses less air than the Regular Air Knife at the same pressure.

Air knife FAQs
1. Will the Air knife operate with a blower?
No. The Air knife is designed to use only compressed air. Blowers are very noisy, large, and expensive with 3″ to 6″ connections. They simply will not produce enough force to operate our Air knife.
2. Can I cut the Air knife to a custom length?
No. The Air knife is precision-machined. Cutting it would expose the internal design with no way to reseal the Air knife. With that said, custom sizes can be machined upon special request.
3. Can I connect the cold end of a Vortex Tubes to an Air knife
No. This would cause an airflow restriction which would instantly produce back-pressure in excess of 5 PSIG! When this back-pressure is exceeded, performance of the Vortex Tube will be negatively impacted. The hot end of the Vortex Tube on the other hand can withstand a pressure up to 30 PSIG (depending on the cold fraction).
4. What is the recommended pressure that should be used with the Air knife?
Always try to use the lowest pressure that is possible for your application. Always use a pressure regulator to increase force/airflow to the point where your application problem is rectified. The maximum pressure of the Air knife is 250 PSIG.
5. How do I mount the Air knife?
The rigid compressed air pipe is the best way to mount the regular Air knife (a.k.a. air curtain). If this is not possible, there are multiple 1/4-20 mounting holes located on the back of the Air knife.
6. Can you make Regular Air knives over 54″ or other lengths you do not stock?
Yes. We have the capabilities to manufacture up to 109″ long Air knives. In addition, any length Air knife can be machined upon special request. Lead time for custom orders is typically 2-3 weeks.
7. What temperatures can your Air knives withstand?
Aluminum Air knife:
275°F (135°C)
Stainless Steel (Type 303) Air knife:
400°F (204°C)
Stainless Steel (Type 316) Air knife:
800°F (427°C)
* Temperatures that exceed 800ºF (427ºC) could produce inter-granular corrosion which could eventually plug the air gap opening.
8. There isn’t enough airflow coming out of my Air knife! Do I need more shims?
Before you increase the standard gap opening of .002″, it’s important to ensure your Air knife is working properly. The low flow can be caused by a clogged filter, undersize lines, undersized air compressor, restrictive fittings or even particles clogging up the gap between the Air knife body and cap.
To verify that full line pressure is available, install a pipe-tee along with a pressure gauge at any one of the inlets of the Air knife. If full line pressure is present and additional flow is needed, turn off the compressed air supply and disassemble your Air knife. Be sure to clean the air knife body, cap and shim before reassembling with the additional shim. Tighten each screw to 7.5 ft/lbs.
9. My Air knife has dead spots. What can I do?
Each and every Air Knife that leaves our facility is tested to ensure proper flow characteristics. We suggest that you examine the below (3) three possibilities that may cause these dead spots.
i) Inspect the Air Knife for direct contamination and/or clogging. Cleaning instructions are found in the Installation and Maintenance sheet supplied with your Air Knife.
ii) Screws may have been over tightened during reassembly or mounting. Screws should be tightened to 7.5 ft/lbs.
iii) Air knife may be undersupplied. Do not use undersized lines, filters or restrictive fittings that may not allow enough airflow into the plenum chamber of the Air Knife.
10. How can I get more force out of my Air knife?
A higher force of air flow can be achieved by increasing the volume of air that’s being throttled through the Air knife. There are (2) two ways to do this:
i) Increase the supply pressure. Maximum safe level is 250 PSIG!
ii) Install additional shim(s).
** Both of the above will have a direct effect on the volume of compressed air that is required to supply your Air knife. Therefore proper plumbing modifications should be taken into consideration.
11. Which way does the airflow form your Air knife need to be pointed?
The STREAMTEK Air knife is not position sensitive. It is effective when pointed in any direction.

CASE STUDIES
Case Study: Drying Aluminum Cans with Air knives
A company that manufactures aluminum cans contacted us with regards to a problem they were having during the packaging process. After manufacturing, the cans need to be cleaned and washed prior to shipment to their customers who then use them to package fruit and vegetables. Due to the cans not being dried properly they were seeing a lot of stress corrosion and this was causing the cans to leak. Also, the cardboard used for packaging the calls was weakened by the leftover water from the cans.
By installing two 12″ Regular Aluminum Air knife on each side of the conveyor and an additional 36″ Regular Aluminum Air Knife along the top, they were successful in stripping the water from the cans being transported down the conveyor. Using our low-cost affordable air knives our customer was able to:
Case Study: Remove Static Electricity from stacks of bags with Ion Air Knife
Although plastic bags are becoming less popular due to environmental concerns, many factories still use them to package their products. This at times, can be quite frustrating when a plastic bag refuses to unfold.
This came up recently when one of our customers ordered our Advanced Ion Air Knife due to problems they had encountered on their packaging line. Previously they were using a vacuuming system that at times would jam when picking up multiple bags that were loaded by the operator. The problem would occur when static electricity would cause the bags to hold together. This caused our customer to incur an additional cost, time and manpower to clear the jams as they occurred.
Our customer placed the order for Advanced Ion Air Knife and received it within 3 days. After a quick installation, the results were visible immediately. Now the operator can load the bags into the packaging machine using the Ion Air Knife to blow ionizing air onto the stack of bags removing the static electricity. Adding Streamtek Corp Ion Air Knife saved our customer time in preparation of the bags then previous vacuum method as well as time and man power that was being wasted clearing jams.
Case Study: Air Knives in Hollywood
A customer from a set in Hollywood called us on Friday evening at 6:45 pm, they were shooting a scene tomorrow afternoon (Saturday). They needed a uniform sheet of air to be projected across the front of the camera lens to protect it from the dust n’ dirt that would become airborne from the intense action scenes
I recommended that they install our 18″ Advanced Aluminum Air Knife /w Air Filter & Pressure Regulator. The air filter was a critical component in that it would ensure a clean dry source of compressed air was projected in front of the lens! In addition, the Aluminum Air Knife operates at a much lower sound level.
Since we received the call so late in the day, we missed the cutoff time by UPS to ship the package to the customer for a reasonable rate. This wasn’t a problem though, as Streamtek Corp works closely with all the major Couriers (UPS, FedEx, Purolator, DHL, Canpar, USPS, and Canada Post). We were able to ship the package out at 7:45 pm via FedEx at a very reasonable rate for the customer. The customer will receive the package by 10:00 am tomorrow (Saturday).
