  • Sale -39% Dometic BREATHE 4500 Air Purifier [9620000429] Dometic BREATHE 4500 Air Purifier [9620000429]

    Dometic BREATHE 4500 Air Purifier [9620000429]

    BREATHE 4500 Air PurifierWith this easy-to-install upgrade kit for a marine air conditioner, boaters will always breathe clean and healthy air into the boat. Using state-of-the-art ionization technology, the air purifier effectively reduces dust particles, bacteria, mold buildup, and unpleasant odors. A genuine must-need upgrade for a boat's air conditioning system! CleanAirThe Dometic air purifier uses advanced Dometic CleanAir technology. When voltage is applied to the two needle-point brushes, they interact with the oxygen and moisture in the air to produce negative and positive ions. These ions have three positive effects. First, they help reduce bacteria, viruses, and mold by attacking their core structure. Second, the charged ions attract dust particles in the air. This creates larger lumps of particles, which can be easily caught in the AC filter. Third, the ions also break down the molecular structure of volatile organic compounds. This eliminates unpleasant smells caused by chemicals or waste.Easy & Flexible InstallationCompact in size, the Dometic BREATHE 2500 air purification add-on kit requires little space. This opens various installation options—fan, ductwork, transition boxes, or directly behind the air outlet grille. Thanks to the wide input voltage range (70 to 240 V AC), the system is compatible with most Dometic rooftop air conditioners. The installation itself is quick and easy. Simply attach the base unit with the two bolts or the double-sided adhesive tape included in the delivery kit. Then drill two holes spaced about 2–3 inches apart and press in the rubberized ionizer brushes. Finally, connect the system to a power source. A smart option is to connect the Dometic Breathe air purifier directly to a fan power source. This will ensure you only generate ions when needed.Features: High-Quality Aluminum Inserts (secure, corrosion-resistant mounting) LED Pilot Lamp (clearly indicates that the air purifier is operating) The latest bipolar ionization technology reliably reduces dust particles, bacteria, mold buildup, and odors Easy installation with flexible mounting options: fan, ductwork, transition boxes, or directly behind the air outlet grille No consumables or replacement parts are required; simply clean the ionizer brushes Energy-saving – can be connected directly to the fan to ensure power supply only when needed Compact and space-saving design Universal power supply – wide input voltage range (100 to 245 VAC) Fits Dometic FreshJet 1100, 1500, 1700, 2000, 2200, 3000, and 3200 Specifications: Model: Breathe Model on Label: BREATHE 4500 MARINE Scope of Delivery: Air purifier, screw 2pcs, double tape 4pcs, connection cable 1pc Product Description: Air purification add-on kit Certificates: ECE R10UKCACBEMCUL Dimensions: Dimensions Product Depth: 96 mm Dimensions Product Height: 40.50 mm Dimensions Product Width: 138.50 mm Net Weight, [kg]: 0.36 kg Electrical: Input Voltage (AC), [V]: 100-240 Input Frequency, [Hz]: 50/60 Logistics: EAN-13: 4015704293562 Dimensions Parcel Depth: 236 mm Dimensions Parcel Height: 50 mm Dimensions Parcel Width: 215 mm Parcel Weight: 0.59 kg Specifications: Voltage - Input Range (Volts): 100-240v Box Dimensions: 2"H x 9"W x 10"L WT: 1.3 lbs Owner's Manual (pdf)Brochure (pdf)
