Jabsco 35400 Series Flangemount 4 in Blower, 250 CFM, ISO 8846

Overview

The Jabsco 35400-Series is a 4 inch flangemount ventilation blower for moving air through engine room, fuel compartment, galley, head, and bilge ventilation ducting on boats. It delivers 250 CFM of open air flow, equal to about 7.0 m³/min, and is offered in 12 VDC and 24 VDC versions so it can match the vessel’s DC electrical system.

This blower mounts to a flat bulkhead surface, with the outlet flange fixed at the bulkhead and a slip-on inlet connection for 4 inch ducting. That layout keeps the installation clean and helps route ventilation ducting with fewer bends, which matters in engine spaces and bilge areas where vapor extraction depends on practical hose routing.

The reinforced plastic housing, corrosion-resistant materials, and NMMA type acceptance make the 35400-Series a good fit for marine ventilation work where spray, vibration, and confined spaces are part of normal use. It meets USCG 183.410 and ISO 8846 MARINE for ignition protection and also complies with ISO 9097 MARINE.

Key features

• 250 CFM air flow for high-volume air intake or extraction through 4 inch ventilation ducting.
• Flangemount outlet installs directly to a flat bulkhead for a tidy layout with discharge ducting on the opposite side.
• Slip-on inlet ducting connection supports straightforward routing in engine rooms, bilges, galleys, and heads.
• Reinforced plastic housing with corrosion-resistant materials throughout for marine compartment use.
• NMMA type accepted and compliant with USCG 183.410, ISO 8846 MARINE, and ISO 9097 MARINE.
• 12 VDC version draws 12A and uses a suggested 15A fuse; 24 VDC version draws 5.3A and uses a suggested 7.5A fuse.
• Weighs 6 lb, or 2.7 kg, which is useful when planning bulkhead mounting and access for service.

Variants

The 35400-Series is offered in two electrical configurations for different DC systems. Both variants are the same 4 inch flangemount blower style and share the same 250 CFM air flow rating.

The voltage, current draw, and suggested fuse size vary by configuration. Matching the blower voltage to the vessel’s DC supply is the key difference when specifying this series.

• 35400-0000: Voltage 12 VDC. This version is for 12 VDC systems and is rated at 12A draw with a suggested 15A fuse.
• 35400-0010: Voltage 24 VDC. This version is for 24 VDC systems and is rated at 5.3A draw with a suggested 7.5A fuse.

Installation and setup

Install the blower on a flat bulkhead surface in the upper part of the compartment, away from spray or deck wash. The inlet ducting should be routed with as few bends as possible toward the lower third of the bilge area, where fuel vapors are more likely to collect, while staying high enough that it will not sit in bilge water.

For wiring runs up to 25 ft, use stranded copper wire sized for the selected voltage: 12 gauge for 12 VDC installations and 14 gauge for 24 VDC installations. Longer wire runs call for larger wire, and the circuit should be protected with the correct fuse for the selected model.

Use on board

This blower suits boats that need forced ventilation for engine spaces, fuel compartments, galleys, heads, or other areas where air needs to be exchanged through ducting. It is primarily meant for intermittent operation, such as clearing fuel vapors from bilge areas before starting engines.

It can also be used for general air circulation where the duty cycle is acceptable, but it is not the right choice for applications that require continuous-duty operation. Keep it away from direct heat above 130°F, or 55°C, to protect the blower wheel and housing.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
