No HEPA, No Problem: The ESP-Only Approach in the Souniny Prince Series

Learn how the Souniny Prince Series ESP purifier captures grease without HEPA cartridges, reducing maintenance costs while delivering 95% purification for commercial kitchens.

No HEPA, No Problem: The ESP-Only Approach in the Souniny Prince Series

HEPA cartridges are effective but expensive to replace. The Souniny Prince Series takes a different approach — pure electrostatic precipitation with no HEPA, keeping maintenance simple and cost-effective.

No HEPA, No Problem: The ESP-Only Approach in the Souniny Prince Series

Product Overview

The Prince Series (KL-D-Y16X / Y20X / Y24X) is a slim ductless purifier built around an ESP field with an LCD control panel. Unlike HEPA-based units, it carries only the electrostatic cell, which keeps maintenance simple and cost-effective for everyday grease capture. The SUS201/304 housing is corrosion-resistant and easy to clean, while the digital panel makes speed and status clear at a glance. This series suits shops that want a compact, reliable purifier without the recurring cost of filter cartridges. UV light can be added on request for additional treatment, though activated-carbon modules are not supported on this series.

Maintenance & Filter Care

The electrostatic precipitator cells should be cleaned at regular intervals based on cooking intensity and grease load. In typical commercial operation, periodic washing keeps purification efficiency at its rated level. For units with activated carbon deodorization modules, replace the carbon when odor breakthrough becomes noticeable.

We recommend establishing a preventive maintenance schedule tailored to your daily cooking volume. Souniny provides replacement cells, carbon cartridges and spare parts to keep your system running at peak performance. Contact our service team for guidance on setting up a maintenance plan.

Applications

Medium-duty commercial kitchens, shopping mall food courts, quick-service restaurants and chain stores seeking low-maintenance grease capture without HEPA replacement costs.
