There are obvious differences between explosion-proof fans and non-explosion-proof fans in terms of product research and development, design, and manufacturing.

1. Motor Application

Explosion-proof fans require explosion-proof motors, which refer to motors that can be used normally in various special environments, including high-temperature and flammable environments.

Non-explosion-proof fans use ordinary motors.

2. Impeller Differences

The impeller material of explosion-proof fans must undergo fireproof treatment to ensure that the surface does not generate sparks when exposed to flammable substances. It is typically made of high-quality flame-retardant alloy materials.

The impeller materials for non-explosion-proof fans have relatively lower requirements.

3. Housing Differences

The housings of both explosion-proof and non-explosion-proof fans are volute-shaped. In terms of material selection:

Explosion-proof fans have metal housings with higher hardness, preventing deformation under external force and blocking fire sources from directly entering the fan through the housing.

Non-explosion-proof fan housings do not prevent combustion.

4. Inlet and Outlet Duct Differences

Explosion-proof fans have inlet and outlet ducts with iron inner walls and aluminum rings installed. This design prevents fire sources at the outlet from being transmitted to the fan's interior through air pressure, effectively isolating open flames and flammable materials.

Inlet and outlet ducts of non-explosion-proof fans are generally untreated and do not provide safety protection.
