PVC 770 Series Housings
| 707N | 770 |
Headline 770 series is specifically designed for petrol engine analysis and, uniquely, has a coalescing pre-filter and particulate final filter in one housing. The housings are designed so that the inlet, outlet and drain connections are permanent and the element change is very simple. The two filter elements have different lengths and cannot be installed incorrectly. 770 series housings replace the usual two housing installation, giving benefits of low cost, fast response time and ease of service.
These housings are sold singly or in packs of 25.
Principal Specifications

PVDF Housings
| All PVDF (Kynar) construction Viton Seals Excellent chemical resistance |
||
| 705K | 760K |
PVDF housings are specified in applications where chemical resistance is of prime importance. To preserve the exceptional chemical resistance of the housing, only PVDF bonded disposable elements (K-type for particulate removal, C-type for coalescing) or PTFE elements should be used.
Principal Specifications

Polypropylene Housings
| All polypropylene construction Polycarbonate bowls available Low cost Ideal for portable analysers Good chemical resistance |
|||
| 755P | 750PC | 780P |
Headline’s range of polypropylene housings are available with a choice of polypropylene or low cost transparent polycarbonate bowl. Each housing configuration is available without a drain for particulate filtration, or with a manual drain for coalescing applications. These housings are widely used in low pressure systems requiring low cost filters, with the good chemical resistance polypropylene provides.

Nylon Housings
| All nylon housings Nylon / PC also available Low Cost Ideal for automotive use |
|||
| 750NC | 760N | 775NC |
Depending on the chemical nature of the gas being filtered, other plastic filter housings should be considered e.g. polypropylene, or PVDF. The convenience of complete disposability and low initial cost may make Headline’s DIF’s a more suitable product option. Housings accepting elements 12-32 & 12-57 are sold singly or in packs of 100. Housings accepting elements 25-64 & 25-178 are sold singly or in packs of 25.

Nylon Housings
| All nylon housings Nylon / PC also available Low Cost Ideal for portable analysers |
|||
| 705NC | 710N | 730N |
Headline nylon housings are available in two versions: all nylon with transparent nylon bowl, or with lower cost polycarbonate bowl. Housings for element sizes 12-32 to 25-178 are available, either with a manual drain valve or with no drain. These housings are widely used in low pressure systems where plastics can be specified.
Principal Specifications

PTFE Housings with Glass Bowls
| Virgin PTFE construction Pyrex glass bowls 7 bar pressure rating Element can be monitored visually |
||
| 122PG | 130PG |
The Headline range of PTFE housings is extended by the availability of these versions with pyrex glass bowls. The condition of the filter element can be monitored visually which is important in systems where slugs of condensate may occur.

PTFE Housings
| Virgin PTFE construction Viton seals 7 bar pressure rating Excellent chemical resistance |
|||
| 122P | 132P | 142P |
Headline PTFE housings are designed specifically for use in high chemical resistance or very low adsorption applications. They are used with Kynar bonded disposable elements for particulate removal or coalescing applications. Where only PTFE is allowable, sintered
PTFE elements should be specified.
Principal Specifications

PTFE Filter Elements
PTFE filter elements are produced by sintering pure PTFE granules, no other substances are used in the construction. These filter elements are usually offered when only 100% pure PTFE can be used. It is normally preferable to offer a K type disposable filter element, if suitable, as both pressure drop and life characteristics are superior to the PTFE elements. The advantage of PTFE is a higher maximum temperature, up to 200°C, and somewhat better chemical resistance. These filter elements should be ultrasonically cleaned to give best results.
