Marine Ventilation Fans — Axial, Centrifugal & Blower Systems

Need CCS-Approved Ventilation Fans for Engine Room, Cargo Hold, or Accommodation?

Marine ventilation is a class requirement, not an option — and every space on a vessel has specific airflow, pressure, and fire-safety requirements that general industrial fans cannot meet. hicool supplies 25 configurations of CCS-approved marine axial fans, centrifugal fans, and blowers designed for engine room ventilation, cargo hold air exchange, accommodation HVAC supply, and pump room gas extraction.

Marine Ventilation Fans — Axial, Centrifugal & Blower, CCS Approved

Our marine fan catalogue covers three main categories across 25 product configurations: axial-flow fans for high-volume engine room and cargo hold ventilation, centrifugal fans for duct-based HVAC and high-pressure extraction systems, and portable/fixed blowers for tank ventilation and emergency use. All products are designed per CCS Marine Product Rules and can be supplied with the manufacturer’s BV, ABS, DNV, LR, NK, KR, RINA or RS certificates as required by class.

Axial fans are available in direct-drive and belt-drive configurations, with impeller diameters from 300 mm to 1,600 mm. Centrifugal fans include single-inlet and double-inlet designs with backward-curved or forward-curved impellers for different pressure/flow requirements. All fans feature marine-grade IP56 motors, vibration-dampening mounts, and corrosion-resistant construction (epoxy-coated steel or optional stainless steel for chemical tankers).

Fire dampers, silencers, anti-vibration mounts, and transition ductwork are available as accessories. We supply both individual fans and complete ventilation system packages matched to the vessel’s ventilation schedule.

Product Range Overview

Axial vs Centrifugal — Which Fan Type Do You Need?

Rule of thumb: Use axial fans for engine room and cargo hold ventilation where high air volume matters more than pressure. Use centrifugal fans for ducted HVAC systems, accommodation zones where noise is critical, and any system requiring static pressure above 500 Pa.

Common Applications

• Engine room supply and exhaust ventilation (SOLAS requirement)
• Cargo hold ventilation for bulk carriers and general cargo vessels
• Accommodation HVAC air handling (centrifugal type with silencers)
• Pump room gas extraction on tankers (explosion-proof type)
• Emergency/portable tank ventilation for confined space entry
• Galley exhaust and laundry ventilation

Recent Supply Example
