Easy-release nozzles are installed to simplify servicing and maintenance. In addition, the bearing is designed to operate without the need for grease lubrication or plating; it is cooled and lubricated solely by a small flow of water. As a result, the bearing’s service life is extended by several years compared to similar models, while overall maintenance requirements are significantly reduced. This unit can be supplied with either a European gear motor or an Iranian worm gear motor. All units are equipped with a backwash pump and a backwash filter to minimize the need for nozzle servicing.
All drum filters manufactured by Persian Aqua are produced in two configurations: a channel-installed model and a closed drum model designed for in-line pipeline installation. Drum filters intended for channel installation require a dedicated installation space to be constructed at the project site using masonry materials, concrete, or similar methods. After the installation area is prepared, the drum is positioned in place, and water continues its flow through the drum filter along its designated path. Closed drum filters, also known as closed or in-line drum models, are equipped with an integrated water tank and do not require any special construction work. In these systems, only the water inlet and outlet pipelines are connected to the drum filter, after which the unit is ready for operation.
