{"product_id":"qbp183372","title":"Jabsco 35760 Series DC Flangemount Blower, 4 in, 250 CFM, Continuous Duty","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e250 CFM airflow, equal to 7.0 m³\/min, for moving fumes and warm air out of enclosed spaces.\u003c\/li\u003e\n\u003cli\u003eContinuous-duty DC operation for ventilation setups that run longer than short pre-start blower cycles.\u003c\/li\u003e\n\u003cli\u003eFlangemount housing fastens directly to a flat surface, helping keep duct runs simple and secure.\u003c\/li\u003e\n\u003cli\u003e4 inch duct connection with slip-on inlet ducting for common marine ventilation layouts.\u003c\/li\u003e\n\u003cli\u003eReinforced thermoset plastic housing with corrosion-resistant materials throughout for use in damp marine compartments.\u003c\/li\u003e\n\u003cli\u003e5,000-hour motor rating for heavy service applications.\u003c\/li\u003e\n\u003cli\u003eMeets USCG regulation 183.410 and ISO 8846 marine ignition protection requirements.\u003c\/li\u003e\n\u003cli\u003eNMMA type accepted and compliant with ISO 9097 Marine, EN 60945, EN 61000-6-1, and EN 61000-6-3.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e35760-0092: Voltage 12 VDC. This version draws 11 amps and uses a 15 amp fuse, making it the match for 12 volt DC ventilation circuits.\u003c\/li\u003e\n\u003cli\u003e35760-0094: Voltage 24 VDC. This version draws 6 amps and uses a 10 amp fuse, making it the match for 24 volt DC ventilation circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eFor 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"12 VDC","offer_id":52581964677301,"sku":"QBP183372-V1","price":424.99,"currency_code":"USD","in_stock":true},{"title":"24 VDC","offer_id":52581964710069,"sku":"QBP183372-V2","price":422.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334411_qbp183372.png?v=1780201836","url":"https:\/\/www.qualityboatparts.com\/products\/qbp183372","provider":"Quality Boat Parts","version":"1.0","type":"link"}
