The abbreviations represent the following β-values resp.

finenesses:

For EXAPOR® MAX- and Paper elements:

5 E-X = β5 (c) = 200 EXAPOR®MAX
8 E-X = β8 (c) = 200 EXAPOR®MAX
Filtration ratio β for particles > x µm

12 E-X = β12 (c) = 200 EXAPOR®MAX

Efficiency [%]

16 E-X = β16 (c) = 200 EXAPOR®MAX

30 P = β30 (c) = 200 Paper
Based on the structure of the filter media of the 30 P paper
elements, deviations from the printed curves are quite probable.

For special applications, finenesses differing from these curves

are also available by using special composed filter media.

All filters are delivered with a plugged clogging indicator connection M 12 x 1,5. As clogging indicators either manometers or electrical pressure
switches can be used. Optional extension pipes adapt the filter length to various tank depths. For ordering of accessories please use the below
mentioned codes.

Order example: The filter E 210-66 has to be supplied with an extension pipe (EV) for a mounting depth of 300 mm.

Order description: E 210-66 / EV 300

Part No. (Basic unit)

Extension pipe (4 various lengths are available)

E 210 / E 211: EV = K + 95 / + 195 / + 295 / + 395
E 221: EV = K + 139 / + 239 / + 339 / + 439
(see dimensions and measurements)

For the appropriate clogging indicators see catalogue sheet 60.20.

Remarks:
• The switching pressure of the electrical pressure switch has always to be lower than the cracking pressure of the
by-pass valve (see Selection Chart, column 7).
• The clogging indicators are optionally available and will then be loosely provided.
• The filters listed in this chart are standard filters. Other designs available on request.

Quality Assurance

Quality management according to DIN EN ISO 9001 ISO 2942 Verification of fabrication integrity (Bubble Point Test)
ISO 3968 Evaluation of pressure drop versus flow characteristics
To ensure constant quality in production and operation, ISO 16889 Multi-Pass-Test (evaluation of filter fineness and
ARGO-HYTOS filter elements undergo strict controls and tests dirt-holding capacity)
according to the following DIN and ISO standards:
Various quality controls during the production process guarantee the
DIN ISO 2941 Verification of collapse/burst resistance leakfree function and solidity of our filters.
DIN ISO 2943 Verification of material compatibility with fluids
DIN ISO 3724 Verification of flow fatigue characteristics

Our engineers will be glad to advice you in questions concerning filter application, selection as well as the cleanliness class of the filtered medium attainable
under practical operating conditions.
