Jabsco 35760 Series DC Flangemount Blower, 4 in, 250 CFM, Continuous Duty

Overview

The Jabsco 35760 Series is a DC flangemount continuous-duty 4 inch blower for boat ventilation systems that need steady air movement through engine spaces, bilges, and enclosed machinery areas. It moves 250 CFM, or 7.0 m³/min, and is offered in 12 VDC and 24 VDC versions so it can match the vessel’s electrical system without changing the basic blower configuration.

This is the flangemount version, with the discharge side secured to a flat bulkhead or panel and the inlet connected to 4 inch ducting. The 35760 Series uses a reinforced thermoset plastic housing, corrosion-resistant materials throughout, and a motor rated for 5,000 hours, making it a practical fit for demanding ventilation duty on gasoline-powered boats and other marine installations where air exchange is not just occasional.

Key features

• 250 CFM airflow, equal to 7.0 m³/min, for moving fumes and warm air out of enclosed spaces.
• Continuous-duty DC operation for ventilation setups that run longer than short pre-start blower cycles.
• Flangemount housing fastens directly to a flat surface, helping keep duct runs simple and secure.
• 4 inch duct connection with slip-on inlet ducting for common marine ventilation layouts.
• Reinforced thermoset plastic housing with corrosion-resistant materials throughout for use in damp marine compartments.
• 5,000-hour motor rating for heavy service applications.
• Meets USCG regulation 183.410 and ISO 8846 marine ignition protection requirements.
• NMMA type accepted and compliant with ISO 9097 Marine, EN 60945, EN 61000-6-1, and EN 61000-6-3.

Variants

The 35760 Series is offered in two voltage configurations. Both variants are flangemount 4 inch blowers with the same 250 CFM airflow rating and 6 lb, or 2.72 kg, weight.

The voltage, current draw, and recommended fuse size change between the two versions, so the correct variant depends on the boat’s DC system and the circuit protection planned for the installation.

• 35760-0092: Voltage 12 VDC. This version draws 11 amps and uses a 15 amp fuse, making it the match for 12 volt DC ventilation circuits.
• 35760-0094: Voltage 24 VDC. This version draws 6 amps and uses a 10 amp fuse, making it the match for 24 volt DC ventilation circuits.

Installation and setup

The blower should be mounted on a flat bulkhead surface in the upper part of the compartment, away from spray and deck wash. For flangemount installation, the bulkhead cutout is 3-5/8 inches, and the blower is secured with washers and No. 10 screws tightened evenly to avoid stressing the flange.

The inlet ducting should be routed with as few bends as practical and led toward the lower third of the bilge or engine compartment, where gasoline vapors may collect. The pickup should remain below the top of the engine stringers but high enough that it will not be submerged in bilge water.

Electrical and system integration

For wire runs up to 25 ft, the 12 VDC version uses 12 gauge marine-grade copper wire, while the 24 VDC version uses 14 gauge marine-grade copper wire. Longer runs call for larger wire to limit voltage drop. The positive side of the circuit should include a rated on-off switch, and the circuit must be fuse protected according to the selected voltage variant.

This blower suits boats that need a dedicated engine room or bilge ventilation blower with verified ignition protection and a flange-style mounting layout. It is especially relevant for refits where the existing ducting is 4 inch and the installation calls for a blower that can be secured directly to a flat surface rather than suspended in-line.

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.
