WFIFC stainless steel cyclone separators up to 14 bar
The WFIFC cyclone separator is the first stage of the WFIF range. Instead of a filter element, its stainless steel housing holds a cyclone element that separates condensate droplets — water and oil droplets — from the air before they reach the elements after it.
The WFIFC separator comes in 10 sizes (DN15 to DN80) with flows of 2,500 to 60,000 l/min at 7 bar; working pressure up to 14 bar. It is one of the stages of the WFIF filters — the housing is the same for all stages, but instead of an element it has a cyclone element.
WFIFC separators by size
The size determines the connection and the flow. Each size has its own spare cyclone element.

The flows apply to a pressure of 7 bar and a temperature of +20 °C. Dimensions according to the manufacturer’s technical data sheet; you will find further data on the product page of each separator.

When to use it
The cyclone separator is suitable at the start of the filtration where condensate droplets enter the air line. The separated condensate is drained at the bottom of the housing.
It does not trap fine solid particles or oil aerosol; the manufacturer does not state an ISO 8573-1 class for it. The cyclone element withstands +120 °C.
Where to place it
At the start of the filtration, before the WFIFN25 coarse filter or the WFIFI20 sintered pre-filter: the elements after it then do not get flooded with condensate as quickly.
Flow by pressure
The catalogue flows apply to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, they are multiplied by the correction factor: 1.88 at 14 bar.

Cyclone element, condensate drainage and maintenance
A cyclone element is fitted in the housing — for example, the WFC-010V for the WFIFC-010. The same cyclone element also fits the WFITC-010, WFIWC-010 and WHFITC-010. The cyclone element withstands +120 °C.
The separator is supplied with a cyclone element, without a condensate drain. For WFIF filters, the manufacturer offers the AOK20SS stainless steel float drain up to 20 bar and +65 °C and, for the head, the MDHI 50-K differential pressure gauge. The drain outlet in the bottom has a G 1/2" thread, G 1" for sizes from DN100.
Once a year, check the housing for visible damage.
Accessories for WFIFC separators
MDHI 50-K gauge
Differential pressure gauge with connecting tubes; it shows how clogged the element is.
The same stage in other ranges
Stage C also comes in the WFITC separators up to 14 bar, WFIWC separators up to 14 bar and WHFITC separators up to 50 bar. The cyclone elements are the same for all ranges.
Ventilek’s tip
Condensate first. When water droplets enter the air line, put the cyclone separator C at the start. The elements after it then do not get flooded as quickly.
- Does the WFIFC separator have a filter element?
- No. Instead of an element, it has a cyclone element that separates condensate droplets from the air.
- Does it also trap fine particles?
- No. Solid particles are handled by the meshes and pre-filters, oil aerosol by the fine pre-filter M.
- What temperature does the cyclone element withstand?
- Up to +120 °C.
