Testing rigs are filter testing equipment that are specially designed to carry out filter testing for the rate of flow against -

Pressure drop characteristics
Filtering efficiency
Life characteristics

Variety of filter test rigs are available in the market that can be used for the testing of air, oil and fuel filters. The equipment allows the testing of filters under three different modes, which include

Draw-through (negative pressure)
Blow-through (positive pressure)
Re-circulating

These modes are achieved through different configuration of a set of adjustable air dampers that control the path of the flow. The filter testing rigs can be tailor made by manufacturers as per their unique and specific requirements.

Components
Characteristically a filter-testing rig has following components:

Duct
Filter Accommodating Section
Fan and Fan Control Unit
Inlet and Outlet HEPA Filters

Types of Filter Test Rigs
There are three types of filter test rigs:

Oil Filter Test Rigs: These filter test rigs are used to test lubricate oil filters with the use of either test dust or AC fine test dust and determine the filtering efficiency of the elements to find out the differential pressure drop at various flow rates. These tests have found to be useful in determining the existing life of the filter element of single as well as double life. These filters have found to be highly useful for testing the spin-on oil filter for compression ignition engines and deliver life test, flow and Pressure rate and filtering efficiency.
Air Filter Test Rigs: Air filter test rigs are designed and developed to carry out filter tests to determine the flow rate against pressure drop These test rigs are designed for carrying out filter testing for flow rate against pressure drop features, life features and the filtering efficiency. The air filter test rigs have found applications in automobiles and gas turbines.
Fuel Filter Test Rigs: The fuel filter test rigs are designed and manufactured to test diesel engine fuel filters for compression ignition engines. The fuel filter test rigs can be used to determine life test, flow, pressure rate and filtering efficiency. A variety of valves are provided for controlling at various stages that can be seen in a fitted manometer.

Advantages of Filter Test Rigs
Filter tests are quick, reproducible and repeatable that forms the basic condition for the development and characterization of filters & filter media. Developed as per industry standards, these filters testing equipment can be designed as per the requirements of clients.

Filtration technology is one of the key elements in the protection of environment that provides complete filter test equipment and systems for the development and improvement of filter efficiency and quality control. The components of a filter test rig provide the users with a variety of possible applications.

The filter test rigs offers various advantages like:

Deliver internationally comparable measurement results because of the high distribution of the measurement system
Superior reproducibility of testing technique
Easy to handle and save time
Cleaning and calibration made easy
Low installation time
Low-maintenance
Easy use of measurement technological elements along with other applications
