We evaluate the actual dust concentration, ΔP stability, filter condition, and fan performance.
If dust appears in conveying zones, ducts clog frequently, or ΔP fluctuates significantly, the system no longer meets standards and requires modernization.
In such cases, we recommend a dust-generation audit. 

This depends on the product type, line capacity, and dust load.
SKIF designs solutions based on:

• Uni-F — for most elevator and conveying points

• Cas-F — for fine and problematic dust < 5 μm

• Unload-F — for loading/unloading zones

• Cyclo-F — for pre-separation on large flows

• High-efficiency fans

• STIF explosion protection

After analyzing your process, we select the optimal system with an airflow capacity from 500 to 72,000 m³/h. 

 For a correct aerodynamic design, we require:

• line capacity (t/h or m³/h);

• material type (grain, flour, feed, shavings, etc.);

• layout of process units (elevators, conveyors, separators);

• duct lengths and heights;

• information on existing filters;

• ATEX zoning data.

Based on this information, we calculate airflow, ΔP, and select the appropriate filter type.

Service life depends on dust type and ΔP stability.
In SKIF systems, thanks to pulse-jet regeneration and high-quality filter media, the element lifetime is up to 2× longer than in standard solutions.
Recommended checks:

• ΔP check — once per week

• scheduled maintenance — once per quarter

Yes. In most cases, full replacement is not necessary.
Effective modernization options include:

• adding Cyclo-F units before existing filters;

• replacing old filters with modern Uni-F / Cas-F systems;

• upgrading to a high-efficiency fan;

• optimizing ductwork and stabilizing ΔP.

In around 60% of cases, modernization provides the same effect as a new system but at a significantly lower cost.

 Key performance indicators:

• up to –30% energy savings due to proper aerodynamics;

• reduced product losses (dust returned to the product flow);

• extended filter lifetime;

• less downtime from clogging and overloads;

• ATEX compliance → avoidance of fines and production shutdowns.

On request, we provide a preliminary ROI calculation.

It depends on line capacity, material type, and current equipment condition.
Typical payback period: 8–24 months due to reduced energy consumption, lower product losses, and fewer stoppages. 

 Selection depends on:

• dust type;

• particle size;

• temperature;

• ATEX requirements;

• required airflow.

Typical applications:

• Uni-F — grain, compound feed, conveying points

• Cas-F — fine, explosive dust

• Unload-F — high-precision local aspiration

• Cyclo-F — pre-separation on large flows and filter protection
