Filter Housings Ease of Service for Bag and Cartridge Filters
Wolftechnik offers WTBKF combined ﬁlter housings for bag ﬁlters and cartridge ﬁlters. A high-grade steel casting base ensures that all housing types are constructed in a compact and space-saving manner.
A parts cleaning unit, for instance, clearly shows how innovative, variable products ensure ease of service at the ﬁlter change stage as well as save costs. Due to their favourable cost-throughput ratio, bag ﬁlter housings are often the ﬁrst choice for concept design and subsequent planning of the unit. However, whether the required criteria of the manufactured parts are met is often only demonstrated when the unit is inspected for acceptance by the end user.
In principle, a ﬁltrate quality upgrade involving various ﬁlter media in the bag ﬁlter housing is possible. However, it is better to rely on WTBKF combined ﬁlter housings from the start, states the firm. Without unit modiﬁcations, bag ﬁlter and—in the case of raised requirements—standard ﬁlter cartridges can be ﬁtted in one and the same housing.
A high-grade steel casting base ensures that all housing types by Wolftechnik are constructed in a compact and space-saving manner. It also clearly raises the service friendliness of the unit, opines the company. If the unit was planned with standard bag ﬁlter housings, the ﬁltrate quality and bag ﬁlter lifetime can be increased with a number of innovative filter elements, such as the pleated ﬁlter bags and the Lupus-II-ﬁlter elements. Even the beneﬁts of depth ﬁlter cartridges and pleated filter catridges can be used.
As such, by using 1-layer pleated ﬁlter bags of the WFB-1AP type, the lifetime is increased in line with the larger ﬁlter surface. Along with the lifetime, the retention rates are also improved from the use of 2-layer bag ﬁlters with internal pleating of type WFB-2IP.
According to the firm, a further qualitative upgrade in ﬁltrate quality and ﬁlter lifetimes comes from using Lupus-II-ﬁlter elements. However, under continuous operations, standard cartridge ﬁlters would be considerably less expensive to maintain than the Lupus-II special products due to their larger ﬁlter surface and longer lifetimes. The experts of Wolftechnik therefore recommend planning with WTBKF-bag-cartridge-ﬁlter housings from the very beginning of the unit concept stage.
