Explosion-Proof Exhaust Fans: Pricing, Airflow Chart & RFQ

In hazardous locations, proper ventilation is not optional—it’s a critical safety requirement. An explosion-proof exhaust fan is specifically designed to prevent sparks or hot surfaces from igniting flammable gases, vapors, or dust in industrial environments. These fans comply with stringent safety standards, ensuring reliable performance in refineries, chemical plants, and offshore operations.

But what determines the explosion proof exhaust fan price, and how do you select the right model based on CFM (Cubic Feet per Minute) and ESP (External Static Pressure)?
This guide covers everything—from pricing to performance charts and lead times—to help you choose the right system and request an accurate RFQ (Request for Quote).

Explore certified explosion-proof fans designed for hazardous environments.

What Is an Explosion-Proof Exhaust Fan?

An explosion-proof exhaust fan is a ventilation system built to operate safely in areas where flammable gases or vapors may be present. Unlike standard fans, these units feature spark-resistant materials, sealed motors, and corrosion-proof housings that prevent ignition from electrical or mechanical sources.

Explosion-proof fans are typically certified under one or more of the following standards:

• NEC Class I, Division 1 or 2

• ATEX / IECEx

• UL and CSA Hazardous Location Approvals

How to Choose an Explosion-Proof Exhaust Fan by CFM and ESP

When selecting an exhaust fan, two critical performance factors to evaluate are CFM (Cubic Feet per Minute) and ESP (External Static Pressure).

What is CFM?

CFM measures how much air a fan can move per minute. Higher CFM fans are suitable for larger spaces or environments requiring rapid air turnover.

What is ESP?

External Static Pressure (ESP) represents the resistance to airflow caused by ducts, filters, and other components in the ventilation system. Fans with higher ESP tolerance perform better under restrictive conditions.

CFM and ESP Selection Chart

Model	Diameter	Free Air CFM	CFM @ 1.0 in. ESP	CFM @ 2.0 in. ESP	Recommended Application
RamFan UB20xx – 8”	8”	980	860	720	Confined spaces, tank ventilation
RamFan AFi50xx – 16”	16”	3,350	3,200	2,800	Industrial exhaust, refineries, shipyards

Selection Tip:

• Use the RamFan UB20xx for small enclosures or portable ventilation.

• Choose the RamFan AFi50xx for large-scale extraction or hazardous storage ventilation.

What Affects Explosion Proof Exhaust Fan Price?

The explosion proof exhaust fan price depends on several variables:

1. Certification Level:

   • ATEX / IECEx certified models typically cost more than standard UL-rated units.

2. Size & Airflow Capacity:

   • Larger diameters (16” and above) with higher CFM output increase cost.

3. Voltage & Motor Options:

   • Dual-voltage or three-phase configurations add to overall price.

4. Accessories & Ducting:

   • Bundled kits or long ducting hoses can increase total package value by 15–20%.

5. Lead Times:

   • Custom configurations or high-demand units may extend delivery by 2–4 weeks.
