Filters for Instrumentation and Gas Analysis

Product catalog summary

Overview: Headline Filters is a prominent European manufacturer with over 30 years of experience in producing filter elements and housings for instrumentation and gas analysis. Their products are used globally across various industrial applications.

Product Specifications: The company offers disposable bonded microfibre filter elements known for their high efficiency, cost-effectiveness, and long service life. These elements are compatible with industry-standard sizes and can fit into housings from other manufacturers. Stainless steel and PTFE filter elements are available for applications requiring high strength or chemical inertness.

Filter Housings: A wide range of filter housings is available, providing flexibility with standard designs and materials. Custom-made options are also offered to meet specific customer needs.

Applications: The products are suitable for various gas filtration applications, including particulate removal and coalescing of liquid aerosols. The choice of filter housing depends on factors such as pressure, temperature, gas composition, contaminants, and filtration duty.

Filter Elements: Disposable filter elements made from borosilicate glass microfibres offer exceptional filtration efficiency. Specific types are available for different applications, such as K Type for corrosive gases and S Type for high-temperature applications.

Stainless Steel and PTFE Elements: Stainless steel elements are ideal for heavily contaminated applications and are easy to clean. PTFE elements are used when 100% pure PTFE is required, offering high temperature and chemical resistance.

Disposable In-Line Filters and Adsorbers: These filters and adsorbers are designed for convenience, with permanently welded housings and encapsulated filter elements, ideal for portable analysers. They offer excellent chemical resistance and are available in various grades and materials.

Vapour Adsorption Cartridges: These cartridges fit standard size filter housings and provide vapour adsorption over a range of line pressures. They are disposable and offer a wide range of adsorbents.

Material Abbreviations: 316L refers to 316L Stainless Steel, and PTFE refers to Polytetrafluoroethene.

Filter Housing Specifications: The document details various series of filter housings constructed from 316L stainless steel, designed to BS5500 standards, and available with Viton or PTFE seals. The housings are CE marked and offer a choice of 2 or 3 ports.

Series Overview:

110 & 120 Series: Suitable for general applications with 1/8” and 1/4” line sizes. The 110 series is recommended for critical response time or space constraints, while the 130 and 140 series are for high flow rates or heavy contamination.
110HP & 120HP Series: Designed for applications between 340 bar and 700 bar, with a maximum temperature of 200ºC. These are also available with PTFE seals.
130 & 140 Series: Ideal for applications requiring 25-64-xx or 25-178-xx sized elements, with a pressure rating of 100 bar.
130HP & 140HP Series: For pressures above 100 bar, with HP series up to 200 bar and VP series up to 400 bar.
Low Pressure Series: Includes models like 117 and 148, designed for low pressure applications with a maximum pressure of 7 bar and temperature of 100ºC.
In-Line Series: Used where element change is not critical, suitable for lightly contaminated gases or as last-chance filters.

Principal Dimensions and Accessories: Each series and model has specific dimensions, volume, and weight. Accessories include standard and high-temperature gasket sets, support cores, and mounting brackets.

Filter Element Codes: Elements are available in disposable, stainless steel, and PTFE variants, with specific codes for each series and model.

Notes: The document advises consulting for exact pressure ratings above 200ºC and specifies that PTFE seals require a modified design and cannot be retrofitted into standard housings.

Principal Specifications: The document lists several models of filter housings, each with specific port sizes, maximum pressure and temperature ratings, materials of construction, dimensions, volume, and weight. The materials used include 316L stainless steel, PTFE, nylon, and polypropylene, each chosen for their specific properties such as chemical resistance or temperature tolerance.

Stainless Steel Fast Loop Series: Models like DV127G, DV137G, and FD130 are highlighted for their stainless steel construction and design to BS5500 standards. These models are noted for minimizing response time and include features like automatic float drains for liquid removal in positive pressure systems.

Heatable Housings: Designed for hot gas analysis, these housings can withstand temperatures up to 200ºC and allow for quick filter element changes. They are constructed from 316L stainless steel and are suitable for applications like diesel exhaust analysis.

PTFE Housings: These are designed for high chemical resistance applications and feature virgin PTFE construction with Viton seals. They are available with Pyrex glass bowls for visual monitoring of filter elements.

Nylon and Polypropylene Housings: These housings are cost-effective options for low-pressure systems. Nylon housings are available with either nylon or polycarbonate bowls, while polypropylene housings offer good chemical resistance and are ideal for portable analyzers.

PVDF Housings: These are specified for applications where chemical resistance is crucial. They are constructed entirely from PVDF and are compatible with PVDF bonded disposable elements or PTFE elements.

Accessories and Element Codes: The document provides details on gasket sets, mounting brackets, and filter element codes, specifying the materials and configurations suitable for different applications.

Filter Housing Models:

770 Series: Designed for petrol engine analysis, featuring coalescing pre-filter and particulate final filter in one housing. Benefits include low cost, fast response time, and ease of service.
200 Series: Aluminium and aluminium/polycarbonate housings used for non-corrosive gas filtration, available with or without drains. Ideal for compressed air filters.
Aluminium Inlet Filters: Offered in open and enclosed designs, suitable for environmental monitoring applications.

Additional Features:

Catch Pots: Used to prevent filter flooding by capturing condensed liquids before filtration.
Bubblers: Allow gas samples to pass through a liquid for washing or adding vapour to the sample.

Flow Rates: The document includes tables showing air flow rates for different filter element grades at various pressures, highlighting the performance of disposable, stainless steel, and PTFE elements.

Filters for Instrumentation and Gas Analysis-31

137GCP A major problem in many gas sample systems is the presence oflarge quantities ofcondensed liquid.In such systems it is possible for a filter to become flooded,even when serviced frequently.A common solution to this problem is the installation ofa catch pot immediately before the filter.Many Headline filter housings can be converted into catch pots,those with transparent bowls (e.g.137G, 250,751N or 780PC) being especially suitable,as they allow continuous monitoring ofthe liquid level.To order catch pots simply add CP to the housing code. > 245BB A further adaption ofthe filter housings...
