Rotary Vacuum Drum Filter
Pharmalab is renowned worldwide as an innovation-driven company and a market leader in various technologically advanced products. Having served the industry for over 6 decades with several filtration solutions, Pharmalab provides an advanced filtration solution with its range of Rotary Vacuum Drum Filter (RVDF).
Rotary Vacuum Drum Filter (RVDF) has typical applications in high-volume filtration for continuous or batch mode of operation. The solid-liquid filtration is carried out using a continuous rotating drum kept under constant vacuum. The system facilitates efficient slurry filtration, cake-washing, dewatering and/or clarification. RVDF offers flexibility of Pre-coat and direct media filtration:
DIRECT MEDIA FILTRATION - FOR SOLID FILTRATION
Solids as desired products can be effectively separated from slurries or suspensions using the direct media filtration technique. Direct Media Filtration is largely used in – final and intermediate filtration of API, starch filtration, solids separation in the agrochemical/chemical/specialty chemical industries.
PRE-COAT FILTRATION ā FOR LIQUID FILTRATION
Fine filtration can be achieved using the pre-coat liquid filtration technique in RVDF.
Precoat filters are used to separate unwanted solids from suspensions. General applications include – charcoal filtration, fermentation broth filtration, juice clarification, purification of insecticides/herbicides,
fermented yeast separation in breweries, wineries, distilleries, etc.

RVDF - Rotary Vacuum Drum Filter
Pharmalab offers industry-based solutions for a wide range of
applications. They are broadly classified as RVDF-GT (Gas Tight) and the RVDF -nGT (non-Gas Tight)
RVDF (GT)
The RVDF-GT is specially designed for applications that require a
completely closed system. This adheres to the strict regulations of the
pharmaceutical industry. The agrochemical, biotechnology, chemicals
and other allied industries find applications of the RVDF GT for their
varied process operations involving solid and/or liquid product
recovery.
Salient Features:
Completely closed (gas-tight) filtration facilitating
- Operation under inert atmosphere (Nā)
- Elimination of product contamination
- Minimal solvent losses.
- Safe handling of hazardous material.
Separate filtrate and wash liquid collection.
Complete heal cake discharge through blow-back arrangement
aids in
- Effective filtration of sticky and challenging products
- Elimination of heal cake reprocessing.
Solid discharge in atmospheric conditions using rotary gas tight
valve.
RVDF (nGT)
The RVDF-nGT is designed for pre-coat filtration and de-watering
applications for the Food & Beverage, Winery, Brewery, Distillery industries, The RVDF offers efficient filtration solution for
extremely clear filtrate requirements.
