Two-stage air cleaners
Two-stage dry air filters guarantee maximum filtering performance under the harshest of operating conditions and heavy dust loads. The first stage is an integral dust collector and the second stage the main filter element with an optional secondary element. The separated dust from the first stage is eliminated directly via the built-in dust expulsion valve. Many VikoPac models have an integral dust collector instead of the direct dust expulsion for applications in which the dust may not be ejected into the working environment again.
JoktoPur compact-two-stage air cleaner with multi-cyclone pre-cleaner in oval plastic housing
The JoktoPur compact-two-stage air cleaner has an integrated high-efficiency multi-cyclone pre-cleaner with an efficiency up to 95%. This compact-filter provides a high airflow capacity and maximum filter lifetime. The oval, compact filter design enables fitting in a tight space area.
To scavenge is better
Scavenging is obtained by introducing a secondary flow (connecting for example to the ejector muffler) to the drop tube on the multi-cyclone block. In this way, the contaminant is sucked into the exhaust stream.
JoktoPur is designed to operate with or without scavenging.
The main advances of scavenging mode are
- Longer filter life service, resulting in higher pre-cleaner efficiency
- The dust outlet tube can be positioned in any orientation
- No maintenance required
Properties
- Vertical and horizontal versions
- Integrated high-efficiency multi-cyclone pre-cleaner
- Two-Stage filtration – axial airflow
- High airflow capacity and maximum filter lifetime
- Low space requirement through oval design
- Integrated mounting brackets on two sides of the body
- Works with or without active dust extraction (Scavenging)
- Increased performance with active dust extraction (Scavenging)
- Integrated connector plug for maintenance switch Sentinel
- Operating temperature from -35°C to +85°C with peaks of +100°C
- Volume flow range from 2m³⁄min to 12m³⁄min (20mbar)

Gecorosso - New VikoSeal filter series for OEM
Gecorosso is the new generation of two-stage air filters with innovative “Compact Lock” technology. These new opening and closing mechanisms allow easy maintenance of the filter elements while taking up less lateral space.
The filter element is manufactured without glue and metal (ultrasonic technology), which ensures sustainability in production and disposal as the elements are fully ecological and made of recyclable materials only.
The filter medium used is mixed with nanofiber and has a hydrophobic property. This enables increased filter efficiency with a lower pressure loss in the same installation space.
Another decisive advantage of the water-repellent filter medium is that the moist dust hardly deposits on the filter medium. This means that the filter performance remains optimal even in a damp work environment.
The unique design, manufacturing process, and filter medium make the elements unique. This guarantees a very high level of after-sales protection.

Filter Accessories
Sentinel electric maintenance switch (sensor)
This built-in sensor monitors the degree of soiling of the air filter and emits a control signal when the predefined end-pressure differential is reached in the filter. The acoustic or optic display that is triggered alerts the operator to the filter soiling, ensuring that servicing can be carried out at the correct point in time.
Properties
- Lightweight yet robust design for extreme operating environments
- Electrical contact with a stabiliser for reducing inherent resonance
- Easy to fit, and deployable with all filter types
- Different starting-pressure differentials, such as 25, 50, 62, and 75mbar (10-120mbar on request)
- Automatic switch reset after the filter has been serviced
- Normally open contact
- Operating voltage 12 to 24VDC
- Connections to IP44 or IP67 (AMP plug)
- Operating temperature from -30°C to +120°C
Sentinel mechanical maintenance switch (sensor)
This mechanical maintenance switch with an optical display monitors the degree of soiling in the air filter and switches its display from green to red when the predefined end-pressure differential is reached in the filter, telling the operator that the filter needs to be serviced. After the filter has been serviced, the maintenance switch must be reset manually again. Depending on the customer’s application, an optical and/or an electric maintenance switch is connected up for each two-stage air filter, so that a signal is visible in the operator’s booth as well as a display directly on the filter.
Properties
- Lightweight but robust design for extreme working environments
- Easy to fit, and deployable with all filter types
- Various starting-pressure differentials, such as 25, 50, 62 and 75mbar
- The switch must be reset manually after filter servicing
- The operating temperature of -30°C to +120°C
Rain caps
The rain cap protects the air filter against the penetration of moisture in the form of rain, snow, and splashed water and prevents bigger objects such as leaves and branches, etc. from getting into the filter, thus extending the servicing intervals. Various sizes are available in metal and plastic.
Mounting bracket for two-stage air filters (VikoSeal and VikoPac)
