What is a spark proof fan?

What is a spark proof fan?

Spark Resistant Fans Spark Resistant Fan Construction is the technical term for industrial fans typically classified as explosion proof exhaust fans. Spark Resistant Construction is an AMCA requirement when dust, fibers, gases, vapors, or liquids could cause an explosion in the case of any kind of spark.

What makes a fan explosion proof?

Explosion-proof fans also use motors that are designed not to produce sparks as they cycle on and off. For added protection, the blades are often made of materials that won’t accumulate static electricity or otherwise become prone to sparking.

Are furnace blowers explosion proof?

Hazardous Location Blowers Are Explosion Proof And Used For Use In Electronic Applications, Vehicle Fume Exhaust Removal, And More. Hazardous Location Blowers are made of cast aluminum material for spark resistance and long lasting durability. Construction is also corrosion resistant in outdoor environments.

What is spark resistant construction?

Spark Resistant Construction (SRC) is intended to minimize the potential for any two or more fan components to generate sparks within the airstream by rubbing or striking during operation. nyb can build fans to meet AMCA SRC specifications, NFPA containment standards, and ATEX requirements.

Does paint booth need explosion proof fan?

Airflow in paint spray booths In a downdraft booth an exhaust fan installed low down pulls out vapor-laden air while make-up air enters from the top of the booth. NFPA regulations also require fans to be explosion-proof and recommend against the use of belt drive fans.

What is explosion proof lighting?

Explosion-proof lights(like our XP162 light shown here) are designed to withstand an ignition of the flammable material that happens inside the light itself, whereas intrinsically safe lights are designed to not carry enough current to cause a spark that could ignite the flammable material.

Is aluminum intrinsically safe?

RE: Intrinsic Safety – Aluminum While aluminum can burn it does not spark like steel. It is soft and has high thermal conductivity so the heat generated from friction will tend to be conducted away rapidly. Also, the ignition point for aluminum is above the melting point.

How do you know if a motor is explosion proof?

An explosion proof motor is clearly marked with a nameplate that identifies its suitability for a given hazardous environment. Depending on the agency certifying the motor, the nameplate will clearly indicate the hazardous location Class, Division, and Group for which the motor is suited.

Are squirrel cage fans explosion proof?

The 3-phase, squirrel-cage, explosion-proof induction motor cutaway supports industrial training activities related to electric motor types, as well as repair and troubleshooting. Explosion-proof varieties limit potential for local ignition due to internal explosions, sparks, or surface heat.

What is an intrinsically safe fan?

The INTRINSICALLY SAFE PNEUMATIC EXHAUST FAN 300MM (12IN) is designed to ventilate confined spaces and increase the flow of fresh air. It will aid in evaporation and drying. It is suitable for hazardous locations.

What is spark C?

AMCA Type C Spark. Type C offers a minimal level of spark resistance and only requires that possible contact between stationary and rotating components be reduced. Typically, this construction includes the use of an aluminum inlet cone and an aluminum rub ring.

How many air changes do I need for a paint booth?

The more current codes require a minimum of 4 air exchanges per minute for wet or solvent-based paints. Powdercoat booths are required to have 60 lfm. Standard Tools uses 4 air exchanges to design our spray paint booths and uses the 100 lfm as a secondary reference.

What does it mean to have a spark resistant fan?

Spark Resistant Fan Construction is the technical term for industrial fans typically classified as explosion proof exhaust fans. Spark Resistant Construction is an AMCA requirement when dust, fibers, gases, vapors, or liquids could cause an explosion in the case of any kind of spark. Additionally, our fans are rated as ATEX explosion proof.

Where can you use an explosion proof fan?

Explosion proof fans or hazardous location fans and blowers are an essential part of a warehouse, plant, mill, spray booth, tank, confined space or any other area where ignitable fumes, gases or dust may be present.

Are there any spark resistant blowers from AirPro?

AirPro custom engineers spark resistant industrial fans & blowers for all special explosion-proof requirements. AirPro also ensures the motors follow the same explosion-proof guidelines when necessary. Spark Resistant Construction is also available for necessary accessories.

What kind of material is used for spark resistant blowers?

Typically aluminum is the non-ferrous material used here. The AMCA “B” spark resistant construction is less protection that AMCA “A” construction, AMCA “B” construction consists of a non-ferrous wheel or bladed and non -ferrous rubbing plate around the hole through which the shaft passes.
