Protect critical equipment with CLER Pro

Data centers require ultra-clean air to protect sensitive equipment and maintain cooling efficiency. Even small amounts of dust and particles can damage servers, reduce cooling performance, and increase energy costs.

CLER Pro removes particles at the source, before they reach your cooling systems and server rooms. Installation takes less than a day and integrates into existing data center HVAC without downtime. After that, it runs continuously without maintenance, removing particles down to PM0.3 automatically.

No filter changes. No cooling efficiency loss. No downtime. Just clean air for critical infrastructure.

Install once.

Run Continuously.

No filter changes.

Our system is maintenance-free, scalable and energy efficient. It's built to handle the demanding conditions of data centers and IT facilities, where clean air is critical for equipment reliability and uptime.

Pre-filtration for data center HVAC

CLER Pro captures dust and particles before they reach your main filtration systems, protecting servers, storage systems, and cooling infrastructure from particle accumulation. This extends equipment life and maintains cooling efficiency.

Data center maintenance costs reduced by up to 60%

Facilities that typically change filters 2 to 4 times per year and perform system cleaning regularly only need service once every 2 to 3 years with CLER Pro.

Integrates into existing data center infrastructure

Our solution works with existing HVAC and cooling systems, improving air quality and equipment protection without requiring structural changes to your facility.

Why CLER works

No filters to change 

No ducts to clean

No interruptions

Cleaner air, continuously

How CLER Pro protects data center equipment

How CLER Pro protects data center equipment

How CLER Pro protects data center equipment

Traditional panel filters and bag filters are supposed to trap dust particles, but filter efficiency drops as they load up. This allows particles to reach servers and cooling systems, while restricted airflow increases energy consumption and cooling costs.

CLER Pro removes particles before they reach your data center filters, maintaining cooling system efficiency and protecting critical IT equipment. The system works so efficiently that filter replacement intervals are extended by years.

Less waste. Lower energy costs. Better equipment protection.

Patented technology Continuous clean air

CLER Pro has three core components that work together.

High-speed rotation creates centrifugal force. Our lamella design separates particles by weight. And the self-cleaning system rinses everything away automatically.

No filters. No consumables.

5000G Centrifugal Force

Our Perpetual Filtration Technology (PFT) spins air at very high speeds, creating forces up to 5,000 g. This separates particles by weight and catches tiny particles down to PM0.5 without using filters.

Lamella Design Precision Separation

Hundreds of cone-shaped plates create 25,000 m² of separation surface. Air passes through narrow gaps where spinning force pushes particles away from the clean air. This keeps low pressure and steady performance no matter how many particles come through.

Self-cleaning technology

CLER's cleaning process uses very little liquid (0.5 dl/month for a 1,000 m² building) to automatically rinse particles from the plates. No manual cleaning. No filter changes. Just continuous operation.

FAQ

How does CLER work without filters?
icon

Instead of trapping particles in disposable filters, our system uses centrifugal force to separate them by weight and density — removing them before they enter the ventilation system.

Can it handle greasy air from kitchens or fast food environments?
icon

Yes. Our solution is designed for demanding environments like Quick Service Restaurants (QSR), where traditional filters clog quickly. It separates even sticky particles like oil and grease, keeping ducts clean.

Is the air really clean enough to reuse?
icon

Yes. The purified air is so clean it can be safely reused in public areas, contributing to energy savings by retaining warmth from exhaust air.

What happens to the particles that are removed?
icon

They’re collected in a self-draining unit and removed from the system automatically. No manual cleaning required.

How sustainable is this solution?
icon

Very. It eliminates the need for disposable filters, reducing waste and CO₂ emissions from manufacturing and transportation. It’s a long-term solution designed with the planet in mind.

Can this be retrofitted to existing systems?
icon

Yes. Our technology can be integrated into most existing ventilation systems to enhance performance and reduce maintenance.

Do I need to replace any parts?
icon

No. The system is entirely filter-free and self-cleaning. There are no consumables or recurring maintenance parts to replace.

Is it more expensive than traditional filtration systems?
icon

No — the cost is comparable to traditional systems. The key difference is that our solution eliminates ongoing expenses like filter replacements and maintenance. You get the same initial investment, but with significantly lower operating costs over time.
