Best Blow Guns Reviewed and Rated
A blow gun is composed of a nozzle or a tip, and is attached to air lines for the control of air discharge and/or manual actuation. They are primarily used for removal of debris, non-contact drying and cleaning, and general industrial or laboratory applications.
You will find blow gunsmostly in mechanic shops, assembly lines, construction sites etc. Most blow guns are made of plastic or metal and include an ergonomic handle or grip. They also have a sturdy metallic nozzle for producing a continuous stream of compressed air.
Air blow guns with in-built fail-safe pressure mechanism can shut off automatically if the lip is blocked or the gun is dropped. Internal pressure relief valves blows off additional pressure before discharge. In the US, blow guns should meet Occupational Safety and Healthy Administration (OSHA) standards, although there are some that exceed the standards. Manufacturers indicate whether a blow gun is suitable for vacuum attachment, or high volume applications, or threaded discharge port.
To ensure that you get the most out of your blowgun, purchase a high-quality and durable blow gun that you can depend on everyday. Our selection of the best blow guns in the market from top manufacturers is second to none.

Types of Air Blow Guns
Air blow guns differ in terms of actuation style and nozzle type. Standard safety straight nozzles deliver an upstream pressure equal to the dead-end pressure, so they are ideal for general-purpose applications. Flat nozzles are used for creating an air curtain or blowing-off large surfaces. Small-diameter nozzles are suitable for inserting into tight openings.
Nozzles with flexible tips can be directed to the application surface while nozzles with rubber tips do not scratch surfaces. Also straight extended nozzles are designed for difficult-to-reach surfaces. A Venturi nozzle with a large diameter contains small openings that allow the discharge to draw enough air for increased airflow.Air screens are used to reduce particle blowback.
In terms of actuation, most blow guns are actuated by the thumb andhave anair supply hose that is in-line with the discharge lever. There are also triggers or pistols -style blow guns, in which the actuator is located at a right-angle to the air hose. Other blow guns are button actuated.

We have made sure that all our selected blow guns have undergone through a rigorous process so that we can come up with an accurate and detailed review of each device. Our evaluation criteria revolved around four factors including:
Air line connection type
When it comes to cleaning using a blow gun, pressure is an important part of the equation. Most companies use the pressure produced by a blow gun as their main selling point. However, some ratings are misleading since the manufactures only state the maximum pressure their blow guns can perform at, but that does not mean it is the actual cleaning power or pressure you will receive. This is because the cleaning power is not determined by the pressure only.
A true indication of the capabilities of a blow gun is determined by its flow (measured in Litres per Minute) and Bar- the pressure produced.
A unit of pressure is measured using a bar where 1 bar is equivalent to 14 pound per square inch (PSI). In general, the higher the PSI and Lpm ratings are, the more powerful the blow gun is. Lpm and bar ratings are mutually important but if one is high while the other is low your cleaning experience can be underwhelming.
For instance, a standard car wash using a blow gun at 10Lpm can require 1820 PSI, while cleaning a driveway at 14 Lpm needs 2100PSI.
The flow rate of a blow gun (measured in Lpm) has as much pressure rating as the impact on cleaning results. The flow rate can vary depending on the cleaning level. For instance, blow gun for home applications available in most hardware has a flow rate ranging from 6 Lpm to 10Lpm. On the other hand, an industrial blow gun can offer flow rates ranging from 10 to 40Lpm.
This is clearly quite a gulf, although most home users do not need much power that industrial blow guns can provide. A balanced and a well ratedblow gun in the lower, Do-It-Yourself blow guns range can offer all of the cleaning force required by most home users.
Since there are many different blow gun models on the market today, choosing the right one for the task can be pretty daunting. However, understanding the differences between them can help you get the best value for your money. Everything comes down to price and performance- everyone is looking for the best performance blow gun at the cheapest price. The best way to know the performance of different blow guns is through a simple calculation known as the cleaning effect.
The Cleaning Effect Equation: Flow (In Lpm)x Pressure (In Bar) /600
Although this calculation does not feature on manufacturer’s boxes, it is a rough and reliable method of measuring the amount of power you can expect. You can break down the calculation results using the following levels, which can tell you exactly how good a blow gun is:
– The blow gun is useable although it has no spectacular results.
1.5 – An average blow gun that can carry out medium-level tasks
2.0 – A top-class domestic blow gun.
2.3+ – A shop machine that can deliver the power you need for your DIY or home-based tasks.
The key to choosing the best blow gun is to find the right cost-to-power ratio that meets your needs. Purchasing the most powerful blow gun does not mean you get the best value: It simply means that you have a powerful blow gun that has overmatched your needs.
Evaluating the perfect blow gun for the intended job is vital. Just like an industrial cleaning staffcannot use a low-powered DIY cleaner, DIY users need not to go for raw power.
Air Line Connection Type
Blow guns use different types of air line connectors. Push-on connectors have barbed ferrules while quick-release connectors feature fittings that are attached internally. Many types of air line connectors are available. Also, there are various types of national pipe thread (NPT) connectors, in which most of them are either female or inch-based. \ NPT measurements include outside diameter (OD) and threads per inch (TPI):
1/4 in. NPT connectors have an OD of 0.540 in. and 18 TPI
1/8 in. NPT connectors have an OD of 0.405 in. and 27 TPI
3/8 in. NPT connectors have OD of 0.675 in. and 18 TPI
1/2 in. connectors have an OD of 0.840 in. and 14 TPI
There are also 10-32 NPT threads. Air line connections with a pivotor swivel are suitable for tasks that require flexible positioning.
Q1. What are the hazards of using a blow gun?
Noise coming from blasts of compressed can result in occupational hearing loss, increased accident risks, and can cause communication barriers. Particles contained in compressed or air projected into the air can cause infections, sores, or irritation if they penetrate your skin or get in contact with your eyes.
If the compressed air from the blow gun gets into your body via your nose, skin, ear, or skin, it can lead to serious injury for instance a ruptured eardrumor oesophagus, sudden or permanent pulmonary embolism or even hearing loss.
Q2. What is a safe blow gun?
In the US, Section 326 of the Regulation in respect to the occupational health and safetyrequires that the pressure of compressed air for cleaning should be less than 200kPa. A blow gun is “safe” if the air pressure at the nozzle does not exceed 200 kPa. When the nozzle id at the dead-end or blocked. This pressure regulation helps to reduce the risk of air or particles from penetrating through the skin.
To meet the requirement, you can utilize a blow gun with extra openings to allow air to escape when the end is blocked. Also, you can install an upstream valve that can constantly limit the air pressure to less than 200kPa.
Putting on protective equipment such as gloves, safety goggles with side shields, hearing protection,and face shields is still required. To reduce noise, you can choose models that are less noisy. A model can produce less noise and still deliver the same thrust. For protection against flying particles, choose a model that can create an air shield or one with a deflector or protective shield that keeps the air or particles from flying towards you.
Q3. What pressure should an air blow gun operate at?
Before advising on any level of pressure, the question to ask is if the operatives are fully aware on how to use a blow gun responsibly and safely.
Areas that should be examined first at all times are whether the air blow guns on site have inbuilt features and whether the right PPE types are specified and worn.
It is likely that there is need to use air blowguns at general factory so that the available energy is enough to perform the work required. Luckily, there are numerous safety type air blowguns on the market although there are still a large number of the old, non-safety models.
It is important to inspect and service blow guns regularly to ensure that they function properly, and that no safety features have been that the guns are regularly inspected and serviced to ensure that they still function correctly and that all the safety features are not overridden. Also, it is important to make sure that the guns are only used for their intended purpose. For instance, if someone has a cut or wound on the arms or hand can sustain severe injuries if a blow gun operating at six bar hits that part.
Another question worth asking is if the staffs using non-safety blow gun models are instructed on how to use them safely. As a rule of thumb, the pressure on such blow guns should be up to two bar and they should wear protective clothing.
Q4. Why does the nozzle rotate?
A blow gun’s nozzle does not require an external power to rotate. The reaction force of the air pressure causes the rotation. For instance, if you attach the hose to a water tap and spray the water vigorously, you will find that the hose end will vibrate irregularly.
Q5.Can you use compressed air greater than 30 psi for industrial applications?
For most pneumatic tools such as blow guns to operate effectively, they require 80-120 PSI. However, they must include an inbuilt air port or relief device to drop the pressure to under 30 PSI once it reaches the dead-end.
Q6. What is the perfect size of hose?
The size of a hose depends on the type of blow gun that you have. You can check your manual to find the appropriate size to use. Generally, the larger the gun, the larger the size of diameter required.
