Bag Filter
Bag Filter
Mechotech engineers and manufactures the Bag Filter as turnkey process equipment for pharmaceutical, nutraceutical, food, and botanical processing lines that need economical, high-capacity particulate filtration. Each unit is designed around the client's specific process parameters and target output, then fabricated, installed, and commissioned by Mechotech as a single accountable scope.
The Bag Filter is built in SS 316L (or a process-appropriate grade) as a vessel housing one or more replaceable filter bags, through which the process liquid passes so suspended solids are retained on the bag media and periodically replaced, with electropolished product-contact surfaces and integrated instrumentation so it can be operated under PLC-based control. Capacity is configured to the customer's requirement, from pilot-scale systems for process validation to larger commercial installations with modular expansion, and every unit is delivered with full documentation to support GMP and regulatory qualification.
Technical Specifications
| Product | Bag Filter |
|---|---|
| Technology | Bag filtration — vessel housing one or more replaceable filter bags |
| Working Principle | The process liquid passes through the bags, so suspended solids are retained on the bag media and periodically replaced |
| Illustrated Configuration | Vertical housing holding four replaceable filter bags, with an inlet, an outlet and a pressure gauge, as shown on the product illustration; the bag count, media and housing are configured to the duty |
| Product-contact Material | SS 316L (or process-appropriate grade), electropolished |
| Automation | PLC-based control with integrated instrumentation |
| Capacity | Configured to the customer's requirement — pilot to commercial, with modular expansion |
| Compliance | GMP hygienic design; full documentation for qualification |
Plant Capacities
| Plant Scale | Capacity | Typical Use |
|---|---|---|
| Pilot | Pilot-scale systems sized to the feed and target output | Process validation, product development |
| Semi-Commercial | Configured between pilot and commercial scale | Scale-up trials, contract manufacturing |
| Commercial | Larger commercial installations with modular expansion | Production at confirmed buyer volume |
Capacity is configured to the customer's feedstock, throughput and target output; we recommend validating parameters on a pilot system before scaling.
Manufacturing Process
Engineering & Design
Mechotech's process engineers size and configure the Bag Filter around the client's feed material, bag count, and target output specification before fabrication begins.
Fabrication & Assembly
The housing and bag support baskets are fabricated in SS 316L (or a process-appropriate grade), with instrumentation and control automation integrated during assembly rather than added afterward.
Operation: Filtration and Bag Change
In service, the process liquid enters through the inlet, passes through the bags and leaves through the outlet while suspended solids stay on the bag media; when the pressure drop across the bags rises, the bags are changed or cleaned (general working principle; the final design is set to the client’s process).
Installation & Commissioning
The completed system is installed at the client's site, and commissioned as a single accountable unit before handover.

Key Features
SS 316L Construction
Electropolished product-contact surfaces, cleaned in place (CIP) between batches, with full documentation to support GMP qualification.
Turnkey Engineering
Design, fabrication, installation, and commissioning are delivered as one accountable scope, so the client deals with a single engineering team from drawing to handover.
Scalable Capacity
The filter is sized to the customer's requirement, from pilot-scale validation through to commercial capacity, with modular expansion as production grows.
