That is a labelling error left over from how our catalogue was built. \u003cstrong\u003eThe unit on this page is the CB-28: a 28\" (711 mm) fan in a fixed-louver housing.\u003c\/strong\u003e Every specification below is the CB-28's own. If you are choosing between the two models, ask us and we will confirm which is which before you order rather than after.\u003c\/p\u003e  \u003ch3\u003eThe one that runs all day without a hose\u003c\/h3\u003e  \u003cp\u003eThe CB-28's real advantage is arithmetic. It holds 80 gallons and draws roughly 2.6 to 3.2 gallons an hour. Even running flat out in the worst of the afternoon, that reservoir is nowhere near empty at the end of a shift — which means this is a cooler you can put in the middle of a space with no plumbing at all and simply use.\u003c\/p\u003e  \u003cp\u003eThat matters more than it sounds. Most evaporative coolers are sold on the assumption of a permanent water connection, and most real workplaces do not have a tap where the heat is. A machine that runs a full working day on a fill can be positioned by where people actually stand, not by where the plumbing happens to be. Give it a garden hose and it auto-refills and manages its own level; take it somewhere with no water and it still works until home time.\u003c\/p\u003e  \u003cp\u003eBoth the fan speed and the water flow are adjustable, so on a moderate day you can throttle the water and stretch that further still.\u003c\/p\u003e  \u003ch3\u003eFour media panels doing the actual cooling\u003c\/h3\u003e  \u003cp\u003eAir is pulled through four Honeycool media pads, each 30\" high, 13\" wide and 6\" deep. As hot air crosses the wetted media, evaporation pulls heat out of it, and it is that surface area — not the fan — that produces the temperature drop. The fan's job is volume: up to 10,645 CFM through a 28\" fixed-louver housing, rated to cover 2,125 square feet.\u003c\/p\u003e  \u003cp\u003eFixed louvers, rather than swinging ones, put the air where you aim it and keep it there. For a fixed workstation, a bay, a bar or a production line, that is usually what you want; swing louvers suit a room you are trying to keep evenly comfortable rather than a place you are trying to cool people standing in.\u003c\/p\u003e  \u003cp\u003eEvaporative cooling has one honest limitation worth stating: it works by adding moisture to air, so it performs best in dry heat and does progressively less as humidity rises, and it needs somewhere for the moist air to go. Open door, open shutter, cross-ventilation. In a sealed room it will disappoint. In a hot, dry, ventilated space it is dramatically cheaper to run than mechanical cooling.\u003c\/p\u003e  \u003ch3\u003ePower, cord and siting\u003c\/h3\u003e  \u003cp\u003eStandard 110V, 60Hz, 1Ph supply through a GFCI plug — a normal socket, no installation, no electrician, no dedicated circuit. The power cord is 15 ft long, which in practice decides where the machine can stand: measure from the socket you intend to use before you decide where it lives, because running an evaporative cooler on a domestic extension lead is not a good idea on any appliance that holds water.\u003c\/p\u003e  \u003cp\u003eThe unit measures 52\" x 37\" x 76.5\" and weighs 275 lbs empty. Add 80 gallons of water and it stays where you put it, so place it deliberately: pointing into the space, with a clear path for air to escape at the far end, and with the intake face not jammed against a wall. Swivel casters make repositioning it easy while it is empty.\u003c\/p\u003e  \u003cp\u003eSound sits between 60 and 100 decibels depending on fan speed. At the top of that range it is a genuinely loud machine — worth knowing if it is going next to a service desk rather than a production line.\u003c\/p\u003e  \u003ch3\u003eWhat else is built in\u003c\/h3\u003e  \u003cp\u003eA negative ionizer runs alongside the cooling, charging airborne particles so dust and allergens settle out instead of circulating — noticeable in a workshop that makes its own dust all day. An 80 watt LED floodlight producing 4,000 lumens is built into the unit, which turns it into working light as well as air movement for an evening event or a yard. Bluetooth stereo audio is included, and control is by soft-touch LED panel or the supplied remote, which has its own holder.\u003c\/p\u003e  \u003cp\u003eThe housing is high-density polyethylene: impact-resistant, with antibacterial properties, and untroubled by being a cabinet full of water in a way a painted steel one would not be.\u003c\/p\u003e  \u003ch3\u003ePerfect for\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003e \u003cstrong\u003eMid-size workshops and two-to-four bay garages\u003c\/strong\u003e that need real cooling over a working area rather than a whole building.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eEvent, hospitality and marquee use\u003c\/strong\u003e — day-long runtime on a fill, plus light and audio from the same machine.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eLoading bays, yards and outdoor work areas\u003c\/strong\u003e where there is no water supply and no chance of ducted cooling.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAnywhere a fixed-louver machine aimed at people\u003c\/strong\u003e beats a system trying to condition the whole volume.\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3\u003eSpecifications\u003c\/h3\u003e  \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eModel\u003c\/th\u003e \u003ctd\u003eCB-28\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eFan\u003c\/th\u003e \u003ctd\u003e28\" (711 mm), variable speed, fixed louvers\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMaximum airflow\u003c\/th\u003e \u003ctd\u003e10,645 CFM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eReservoir\u003c\/th\u003e \u003ctd\u003e80 gallon, auto-refill\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eWater use\u003c\/th\u003e \u003ctd\u003e2.6 to 3.2 gallons per hour\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eMedia panels\u003c\/th\u003e \u003ctd\u003eFour, each 30\" x 13\" x 6\"\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003ePower\u003c\/th\u003e \u003ctd\u003e110V, 60Hz, 1Ph, GFCI plug\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eCord length\u003c\/th\u003e \u003ctd\u003e15 ft\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eUnit size and weight\u003c\/th\u003e \u003ctd\u003e52\" x 37\" x 76.5\", 275 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth scope=\"row\"\u003eShipping size and weight\u003c\/th\u003e \u003ctd\u003e57\" x 40\" x 73\", 294 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e  \u003ch3\u003eCertification\u003c\/h3\u003e  \u003cp\u003eThis unit is described as carrying UL certification and ships with a GFCI plug, which is the combination that matters on a mains appliance built around a water tank.
