Principal Specifications:
The document outlines specifications for four housing models: 116IL-3, 126IL-3, 136IL-3, and 146IL-3. Each model has specific port sizes, maximum pressure, and temperature ratings. All models are constructed from 316L stainless steel and use Viton gaskets.

Port and Pressure Details:
- Port Size: Models 116IL-3 and 126IL-3 have a port size of NPT 1/4”, while models 136IL-3 and 146IL-3 have NPT 1/2”.
- Sample Port Size: All models have a sample port size of NPT 1/4”.
- Maximum Pressure: Models 116IL-3 and 126IL-3 can withstand up to 340 bar, whereas models 136IL-3 and 146IL-3 are rated for 100 bar.
- Maximum Temperature: All models can operate up to 200ºC, with pressure ratings reduced above this temperature.

Materials and Dimensions:
- Construction: All models are made from 316L stainless steel.
- Dimensions and Volume: The document provides specific dimensions (A, B, C, D) and volume for each model, with weights ranging from 0.7 kg to 3.3 kg.

Accessories and Filter Elements:
- Standard Gasket Set: Different gasket sets are specified for each model.
- Filter Element Codes: Options include disposable, stainless steel, and PTFE elements, with specific codes provided for each model.

Design and Application:
- The filters are designed to BS5500 standards and are part of the Stainless Steel Fast Loop Series, aimed at minimizing response time by positioning the filter close to the gas analyser.
- The process gas is pumped through the filter housing at high velocity, with the sample drawn through the filter element for analysis.
