Frequently Asked Questions
Main Topics
Hydraulic Filters
A hydraulic filter is a component designed to remove solid contaminants from the hydraulic fluid circulating in a system. Its objective is to protect pumps, valves, actuators and other components from premature wear or failure.
Contaminants can cause severe damage to the hydraulic system. A good filtration system:
- • Reduces component wear.
- • Improves system efficiency.
- • Reduces unscheduled downtime.
- • Extends the useful life of hydraulic oil.
Depending on the system design, filters can be placed in:
- • The suction line (before the pump).
- • The pressure line (after the pump).
- • The return line (before the tank).
- • As breather filters in the tank.
- • Secondary line filters (bypass or recirculation).
They remove solid particles such as:
- • Metal dust
- • Seal residues
- • Wear particles
- • External contaminants (dust, dirt)
It depends on the environment, use and system conditions, but as a general rule:
- • Change when the differential pressure indicator marks it.
- • Follow the manufacturer's recommended maintenance plan.
- • Never wait for the filter to be completely clogged.
The micron rating indicates the minimum particle size that the filter can retain, measured in microns (µm). For example, a 10-micron filter can trap particles of that size or larger. The smaller the micron rating, the greater the fine filtration capacity.
The following should be considered:
- • System type and operating pressure
- • Fluid viscosity
- • Required cleanliness level (according to ISO 4406)
- • Type of contaminants present
- • Pressure in the pump increases.
- • Fluid flow is reduced.
- • Risk of filter media collapse.
- • Costly damage to system components.
Yes. We manufacture or replace equivalent filters of any brand, according to dimensions, connection type, micron rating, and working conditions. We also develop custom filters for special applications.
A properly filtered system must meet these points:
- • The fluid remains clean longer (verifiable by laboratory analysis or ISO 4406).
- • No frequent failures occur in valves, pumps or actuators.
- • The filter does not reach its maximum differential pressure in a short time.
- • The hydraulic oil shows no visible signs of contamination.

Dust Collectors
A dust collector is a system that improves the quality of air released from industrial and commercial processes by collecting dust and other impurities from the air or gas. These systems are crucial for maintaining a safe working environment and complying with environmental regulations.
Contaminated air enters the collector, where dust particles are separated from the air stream by one or more mechanisms:
- • Inertia (cyclones)
- • Filtration (bag or cartridge filters)
- • Electrostatic precipitation
- • Wet scrubbing
Clean air is released and the dust is collected in a hopper for disposal.
The main types are:
- • Cartridge collectors
- • Baghouse collectors (fabric filters)
- • Cyclones
- • Wet scrubbers
- • Electrostatic precipitators
Each is suitable for different applications and types of dust.
They are widely used in a variety of industries, including:
