The old way: brochure tables and phone calls
If you have ever specified a filter housing for an industrial gas application, the process probably looked something like this: find the right brochure, locate the flow rate table, cross-reference it with your operating pressure and temperature, check whether the material is suitable — and then repeat the exercise for the filter element.
For experienced engineers, this takes fifteen minutes. For someone specifying a filter for the first time, it can take considerably longer. And if your conditions fall between two table entries, you are likely reaching for the phone.
Skip the brochure. Size it online.
Our free Engineering Tool replaces the manual process with a guided wizard. Four steps, no registration, instant results.
How the tool works: four steps to a recommendation
The Engineering Tool walks you through four steps. Each step narrows the selection until only the housings and elements that match your conditions remain.
Select Application
Choose your filtration category — compressed air, vacuum pump exhaust, process gas, or instrumentation.
Define Conditions
Specify gas type, operating pressure (bar), temperature (°C), and contamination types.
Enter Flow Rate
Input your actual volumetric flow in Nm³/hr or m³/hr — the tool handles unit logic.
Get Recommendations
Receive matched housing models, compatible elements, materials, and a direct quote path.
What happens at each step
Step 1 — Application
You choose from four main filtration categories. Your choice determines which product families are considered and which parameters matter most:
- Compressed Air Treatment — coalescing filters, particulate pre-filters, activated carbon adsorbers
- Vacuum Pump Exhaust — oil mist separators for rotary vane, rotary piston, and liquid ring pumps
- Process Gas Filtration — high-pressure housings for natural gas, biogas, hydrogen, nitrogen
- Instrumentation & Gas Analysis — compact inline filters and sample conditioning housings
Step 2 — Gas & conditions
Specify the gas you are filtering, your operating pressure, and your temperature. The tool uses these to determine:
Automatic material decisions
The tool selects housing material (aluminium, carbon steel, 316L stainless, brass), seal type (Nitrile, Viton, PTFE), and pressure rating automatically based on your inputs. You do not need to cross-reference material compatibility tables yourself.
You can also indicate specific contamination types — oil aerosol, particulate, moisture, or chemical vapours — which influences the element type recommendation.
Step 3 — Flow rate
Input your actual volumetric flow rate. The tool cross-references this against each housing model’s rated capacity to find the smallest housing that comfortably handles your flow, with an appropriate safety margin.
Step 4 — Results
The tool presents recommended housings and compatible elements. Each recommendation includes model number, pressure and temperature ratings, port size, element count, compatible element types, and material of construction.
Direct path to a quote
From the results page, click “Request a Quote” and your operating parameters — gas, pressure, temperature, flow rate, application, and contamination types — are automatically transferred to the inquiry form. You only need to add your contact details.
What the tool covers
| Application | Housing Series | Flow Range |
|---|---|---|
| Compressed Air | RF-H-310 to RF-H-395 | 5 – 765 Nm³/hr |
| Vacuum Pump Exhaust | RF-H-420 to RF-H-456 (AL & SS) | 5 – 765 m³/hr |
| Process Gas | RF-H-150 / RF-H-160 series | Up to 150 bar |
| Instrumentation | RF-H-110 to RF-H-140 series | Application-specific |
When the tool is most useful
New installations
Designing from scratch? Enter your conditions and the tool shows only what fits — no browsing through product pages.
Replacement & upgrading
Existing filter undersized or element life too short? Enter your current conditions and see whether a larger housing, different material, or different element type solves the problem.
Quick feasibility checks
Need to know if a standard housing exists for your pressure, temperature, and flow combination before a full engineering review? Get an immediate answer.
What the tool does not do
Limitations to be aware of
The tool provides preliminary sizing based on standard conditions. It does not replace specialist review for:
- Non-standard gas mixtures (H₂S, aggressive chemicals)
- Multi-stage system design (complete treatment trains)
- Custom housings (exotic materials, non-standard ports)
- Element life prediction (depends on actual contamination)
For any of these cases, the tool’s built-in quote request connects you directly with our technical team.
Key Takeaway
The Engineering Tool replaces fifteen minutes of brochure cross-referencing with a two-minute guided process. It handles material selection, pressure compatibility, and element matching automatically — and connects directly to a quote request with your parameters pre-filled.
