filtration-news-rosedale-4MODEL OT
Bag Filter Housing guarantees a 360┬░ positive seal for flows to 100 gpm*

Model OT filter provides optimum filtration performance when combined with Rosedale’s high capacity filter bags. This unique design ensures a 360-degree positive seal and media compression, eliminating the potential for bypass. Unfiltered liquid and debris does not accumulate above the filter bag and contaminate the clean fluid area during change-out. Fluid passes through the bag from inside to outside. The Rosedale Model OT filter ensures an even flow into the filter bag where contaminate is contained for easy disposal.

The Model OT housing is a durable, high capacity filter with an uncompromising welded construction to meet ASME Section VIII Code requirements. The cover is hinged and fastened with swing bolts for quick access and easy bag change-out. They have a high quality electro polished finish to resist adhesion of dirt and scale, making routine maintenance fast and simple. Model OT filters are available in two sizes with flanged or threaded connections.

It can be customized with several options, including gauges and switches. A wide range of filter bags or cartridges (rated 0.5 absolute to 100 nominal) with various surface areas can be utilized in this housing.

PS-740-PPP-356 maximizes dirt- holding capacity and meets LT2 requirements.

PS-740-PPP-356 elements are manufactured in a unique “Y” pleat arrangement that optimizes physical size and maximizes effective surface area. The large surface area provides a low fluid flux rate maximizing dirt containment. The element fits into the Rosedale NCO8135 housing or can retrofit 8302P housings with an adaptor basket. The end caps are heat sealed for high efficiency performance. The O-ring seal insures sealing and eliminates bypass.
