Bag housings type “BG” size 1 and size 2
Putsch® bag housings type “BG”, size 1 and size 2, are particularly high quality housings made of rolled stainless steel for standard size 1 and size 2 bag filters.
The Putsch® bag housing type “BS”, size 1 and size 2, is a stainless steel filter housing with a special focus on economic efficiency without limiting the primary function and the operation. The convenient, simple bag housings are a combination of a welded structure and the less expensive casting process. The Putsch® design engineers focused on the essential tasks of a filter housing, so the options are limited.
The bag housings type “BS”, size 1 and size 2, consist of a cylinder with cover (cast stainless steel) and a support basket (perforated metal plate) and can hold one filter bag.
These filter housings are available in two lengths for the corresponding filter bags size 1 or size 2.
The starting material is stainless steel, partially rolled and partially cast. The cast parts such as the cover and the upper section of the cylinder are standard production parts.
A support basket holder is welded into these cylindrical pressure vessels.
The filter bag is pressed down and sealed by a perforated pressure plate.
The filter basket consists of a deep-drawn perforated plate with a smooth, electropolished surface.
The filter bag receives the required support and cannot burst. The perforated plate has no sharp edges and the lengthwise seam is flush, so the filter bags cannot catch on the support basket or tear.
The solid cover is flanged and is closed with four convenient eye bolts. The folding eye bolts with ring nuts are galvanized steel and protected against corrosion. After releasing, the fitting are folded down and remain there until they are needed again for closing.
A height-adjustable base frame is clamped around the cylinder for installation. The base frame makes it possible to change the height of the bag housing. At the same time, it offers the advantage of radially adjusting the base position or the intake. The unit can easily be mounted into the piping on site by the installer. Each foot features a floor plate with a hole for floor fixing.
The standard version is supplied with a 2″ internal thread intake and outlet or alternatively with a DN 80 flange.
The outlet is welded to the lowest point in the dished end so no socket is required for draining.
The socket on the cover is used for venting. A pressure gage for the pre-pressure can also be screwed in here.
Filter bags size 1 and size 2 from all known manufacturers fit into these bag housings with regard to the diameter and the sealing edge of the filter bag.
Size 1:
Length: approx. 435 mm
Diameter (collar): 180 mm
Bag surface: 2500 cm2
Size 2:
Length: approx. 810 mm
Diameter (collar): 180 mm
Bag surface: 5000 cm2
The bag housings are pressure vessels in the sense of the relevant regulations and corresponding documentation is available.
