The GHT 4x4 is the total traction filter press with high productivity. The filter plates, which are hung from the upper beam, are moved automatically by a rapid shifting device equipped with a carousel system which reduces the filter press opening and closing sequence to the minimum. Four hydraulic cylinders placed on the plate pack corners ensure perfect operation and limited structural stress, even in the most unfavourable working conditions. Different from the traditional push-type systems, the “total traction” system does not transmit any stress to the upper beam, which is only subjected to weight of plates supported from it. In fact, the forces applied by the closing device are subjecting the tie beams to tension, which avoids stress on the frame and consequently, the risk of structural deformation. Effectively guarded moving parts and the use of state-of-the-art electronic interlock systems mean that the GHT 4x4 conforms to the highest operator health and safety regulations. Routine maintenance operations are simple, thanks to easy access to the filter plates, both for inspection and for filter cloth replacement.

AUTOMAT is a side-beam filter press, characterised by functional design and extraordinary versatility.
Thanks to its strong structure and wide range of models the AUTOMAT filter is able to meet any requirement of solid-liquid separation.
AUTOMAT filters offer the highest level of flexibility and production capacity according to the specific requirements of their required applications.
By means of a PLC (programmable logic controller), the AUTOMAT filter can work fully-automatically, with the operator supervising only the cake-discharging phase.

Star Plate and Frame Filter Presses are designed and built to provide you with years of dependable service. Filters are sturdily built, with a rugged carbon steel stand coated in durable epoxy paint. Standard heads, plates, frames, and their components are fabricated from solid bars, plates, and forgings of 304 stainless steel. Heavily reinforced for maximum life, the precision-machined plates, frames, and heads warrant a tight seal and near-zero leakage without gaskets.
Star Filter Presses can be fabricated in 316 and 316L stainless steel, as well as other special alloys upon request.
Applications include:
• Food and Beverage Processing
• Mining and Metalworking
• Pharmaceuticals, Cosmetics, Biotech Processing
• Chemical and Petrochemical Processing
Benefits:
• High sludge capacity
• Low maintenance
• Large filtration surface area
• No gaskets to maintain
• Excellent corrosion resistance
• Withstands temperatures of up to 375ºF (190ºC)
• Easy to operate, simple to clean
• Expandable by adding plates and frames
• Low filter media replacement costs
• Easy to sanitize
• Minimal plate stack drip
• High liquid flow rates
• Portable
New Star PolyPresses are also available for efficient dewatering with high corrosion resistance.

Chamber Filter Presses
Chamber filter presses utilize an advanced frame filter press design. The frames are actually integrated into the two adjacent plates. Whereas the sealing area on the periphery of the plate has a parallel surface, the face of the plate inside the sealing edge is recessed, forming a chamber for the filter cake formation. Typically, the suspension is fed through a channel arranged in the center of the plates and the filter cloth is stretched over the surface of the plates. Studs or corrugations on the plate surface enable the filtrate to be discharged. Options include a cloth sealed against the infeed channel by screws, or a cloth covering both sides of the plate. It is funneled through the inlet channel where a flexible hose-like connection forms the seal. The filtrate is picked up by the studded or ribbed area and discharged via outlet and collecting channels in the corners of the plates.

We manufacture Filter Presses of different capacities, types and from different materials to suit customer needs. The Filter plates are generally made from Virgin Polypropylene, SS, Phosphor Bronze or CI and their size vary from 355 x 355 mm square to 1500 x 1500 mm square. The Presses are generally made as sliding type for small & medium capacities while large plates are hung from overhead I-beam. Plate closing load is applied by Capstan screw arrangement for small presses operating at low pressures while bigger machines are fitted with Hydraulic system for this purpose. We can offer a wide variety of Filter Press to choose for the specific application.

Filter Press Cloths
Filter presses were introduced at the turn of the century and have been around for many years. A filter press contains a series of plates with a filtering surface on both sides. The plates are covered with a press cloth. Many of these plates are pushed together to form chambers with sufficient filtration area for the application. A slurry is forced into the chamber. The press cloth allows the filtrate to pass through, dewatering the filter cake which forms on the press cloth. The cake is discharged by pulling the plates apart. The cycle then repeats itself. Filter presses are among the most versatile of all liquid/solid separation unit operations. They adapt easily to variations in feed concentrations, particle size and other physical properties, delivering very dry cake and high solids capture with low chemical conditioning costs.
Press Types:
- Plate and frame
- Recessed chamber
- Membrane chamber
Typical Applications:
- Silicas / Silicates
- Pigment and dyes
- Chemical processing
