WEH® CNG Particle filters for clean natural gas

WEH® Particle filter remove solid contaminants from natural gas. Contaminants in the gas flow can enter the vehicle‘s storage tank during refueling. The Filter is used for fueling stations as well as for dispensers. The filter is mainly installed as prefilter in the media inlet between inline breakaway coupling and filling hose.

Description

WEH® Filter TSF4 CNG for CNG vehicles (ECE) and CNG fuelling stations - Series

Contaminants in the gas flow can enter the vehicle‘s storage tank during refueling. These dirt particles in the natural gas fuel may cause damage to the sealing components.

WEH, therefore, offers CNG filter for clean natural gas. Solid particles are captured reliably.

The filter element can be removed and is re-usable after having been cleaned.

The TSF4 CNG filter is mainly used for onboard CNG powered vehicles, but can also be used for fueling stations and dispensers.

The TSF4 CNG round filter is available with double ferrule fitting or female thread on both sides or male and female thread. TSF4 CNG T-filter has been specially designed for use in CNG buses and trucks. The filter can be removed for cleaning purposes without tedious unscrewing of the media lines.

Term	Definition
Temperature range	Is the temperature range in which the WEH^® Product can be used.
Media temperature range	Is the temperature range of the medium used, which can flow through the WEH^® Product (may change depending on the time of measurement).
Ambient temperature range	Is the temperature range of the environment in which the WEH^® Product can be used.
Leak rate	Is the leak rate, which the WEH^®Product max. exhibits under intended use.
Max. side load	Is the max. allowable sum of all external forces that may act on the device under intended use. Note:External forces can affect the life time of WEH^® Products and can cause damage. Tensile and transverse loads as well as vibrations and pressure impacts need to be considered, e.g. by user side measures such as on site mountings and similar. Therefore, lateral forces such as whipping hoses or other equipment must be avoided. WEH^® Products should be installed in such a way, that lateral forces which could lead to leakage or damage can not occur.Special applications require a special consultation before selecting the product.

Term	Definition
Suitability for application	When selecting a component, the total system design must be considered to ensure safe, trouble free performance. The correct selection of components, materials, temperature and pressure data as well as the compliance with the WEH specifications regarding installation, operation and maintenance are the responsibility of the customer.
Products with pneumatic actuation	The customer has to ensure there is adequate axial movement when pneumatically actuated WEH^® Products are used in automated systems. Ideally the products should be mounted with a floating joint or introduced individually to prevent the possibly existing clamping jaws getting blocked or jammed in the thread of the test piece.
Storage /life time of components	There are certain requirements for every WEH^® Product. These are described in the corresponding product documentation.
Sealing material	On request the WEH^® Product can be adapted to customer specific applications regarding to the sealing materials used. The clarification of the media compatibility and suitability of the adapted WEH^® Product for the final application is always the responsibility of the end user.

CNG Filtration

CNG filters for protection of the downstream CNG components. Contaminants within the delivery system and the CNG stream can damage the CNG components (dispenser / vehicle). WEH CNG Filters reliably remove these particles in the gas flow thus reducing damage and downtime for the end user. The filter inserts can be easily cleaned.
