HRSM Explosion-Proof

XE HRSM 2000-EXP Mobile Fog Fan - Explosion-Proof Humidification & Cooling System

Manufactured in the USA by Jaybird Manufacturing

The Aquafog XE HRSM-2000-EXP is a mobile fogging system built around Jaybird’s high-output XE centrifugal atomizer and an explosion-proof (hazardous-duty) motor for use in classified or explosion-prone environments. Designed for industrial humidification, evaporative cooling, dust suppression, and chemical fogging, the HRSM-EXP delivers portable high-volume fog production in facilities where standard equipment is not permitted.

Unlike high-pressure nozzle systems or spinning disc foggers, the HRSM-EXP uses Jaybird’s nozzle-free centrifugal atomization technology, producing extremely fine fog while eliminating clogged nozzles and high-pressure pumps.

The HRSM-EXP includes an 18-gallon integrated supply tank, rugged wheeled chassis, and 4-position pivoting fogging head. Water flow is regulated by a quarter-turn ball valve and the system can be operated continuously or automated using a secondary hazardous-duty controller (where applicable).

Part of the Mobile XE Atomizer Family

The XE platform represents our largest atomizer class, designed for maximum coverage and industrial-scale output.

Hazardous-Location Humidification & Cooling Applications

The Jaybird XE HRSM-2000-EXP is engineered for facilities requiring explosion-proof humidification and evaporative cooling in classified or hazardous environments where volatile vapors, combustible dust, or other ignition risks may be present. Using Jaybird’s nozzle-free centrifugal atomizer technology, the HRSM-EXP produces ultra-fine fog and strong air propulsion while avoiding the nozzle clogging and high-pressure maintenance associated with typical misting systems.

Typical applications include:

  • Hazardous-location humidification
  • Dust suppression in explosion-prone environments
  • Evaporative cooling in classified areas
  • Industrial processing facilities with volatile vapors
  • Mines and underground mines
  • Military hangars and aerospace facilities

When explosion-proof equipment is required, the HRSM-EXP provides a rugged, self-contained mobile platform with industrial-scale fog output for demanding environments.

Features & Controls

HRSM-EXP units include an internal feed pump, a manual 1/4-turn flow control valve, and an internal float valve to maintain proper tank water level during operation. Controls are simplified to meet explosion-proof requirements, with no integrated On/Off switch.

  • 1/4-turn flow control valve
  • In-line strainer
  • Internal float valve (automatic water level control)
  • Large tank access lid
  • Garden hose connection

The manual ball valve allows operators to adjust fogging output based on the application. Lower feed rates generally produce a drier, finer fog, while higher feed rates increase output volume for broader coverage.

Flow Control Guide

Valve Position Typical Use Fog Character
Full Open Evaporative cooling, greenhouse cooling, concrete curing, mushroom growing Highest output / heavier fog
Mid Open General humidification, horticulture, wine barrel storage, wood/lumber/paper applications Balanced output / general-purpose fogging
Slightly Open Textile humidification, dust suppression, static control, lighter treatment applications Drier / finer fog

Control Tip: Start with a lower valve setting and increase flow only as needed. This helps maintain finer fog quality and reduces excess wetting.


SST Plumbing Option

The (SST) version includes all stainless-steel plumbing components installed in place of standard brass fittings. This option is recommended when fogging highly corrosive chemicals or sanitation solutions.

  • Replaces standard brass fittings
  • 304 (18-8) stainless steel components
  • Complete plumbing system upgrade
  • Factory installed

Drainage Port

A specially engineered drainage port at the base of the motor allows condensation to escape, helping prevent internal moisture buildup while preserving the motor’s explosion-proof integrity.

  • Extends motor life
  • Made in USA

Flexible Cable

Optional flexible cord packages are available for installations requiring mobility or non-rigid connections.

  • Extra hard usage rated
  • STOW yellow jacket (660V, 60°C)
  • UL / CSA / MSHA / RoHS compliant

How Jaybird Atomizes Water Without Nozzles

Jaybird fog systems use a patented centrifugal atomizing blade developed in 1986. Water enters a reservoir behind the fan blade and is forced through internal channels inside each blade. As the blade spins, centrifugal force drives water toward the blade tips where it exits through precision openings.

At the blade tip, several processes occur simultaneously:

  • The rotating blade atomizes the water into fine droplets
  • A venturi accelerates airflow around the blade
  • A ring of atomizing pins further breaks droplets into fog
  • Particle size is variable and desired size can be controlled by the feed rate

This multi-stage atomization process allows Jaybird systems to produce large volumes of fog while using a simple, reliable design with no high-pressure pumps or clogging nozzles.

The result is powerful fog production, strong air propulsion, and long-term reliability.
