Replacement Industrial Air Filter for ONAN QD Equipment
The E-4551 is one of the K&N replacement filters in our new line of industrial replacement air filters. This filter uses the new K&N hybrid filtration medium which is very strong and incredibly easy to clean. The new hybrid media does not require any oil and is robust enough to be cleaned using power sprayers, pressure washers or standard truck washing equipment. Instead of repeatedly throwing away expensive disposable air filters, now you have a choice! This washable air filter is designed to improve the generator's performance and make filter maintenance a snap. Using a K&N reusable industrial air filter can help reduce waste and the cost of buying disposable filters over and over.
The E-4551 has a height of 4 inches with an outside length and width of 6.75 inches X 4.063 inches and fits Onan QD generator engines that use Onan OEM number 1402897, see the list of engine types below.
