DPT-J Fresh Air Ventilation is a cabinet-style fresh air ventilation unit for projects that need filtered outdoor air, stable airflow and low-noise installation flexibility.
DPT-J Fresh Air Ventilation is designed for fresh-air projects that require multi-stage filtration, stable air delivery and flexible cabinet-style installation.
The unit combines pre-filtration, HEPA filtration, activated carbon filtration and negative ion treatment to support cleaner incoming air in residential, commercial and light project spaces.
Built for multi-stage fresh-air purification, DPT-J combines filtration, cabinet mounting flexibility and low-noise construction for B2B project use.
The metal filter removes large particles, small insects and pollen before air reaches the finer filter stages.
The pre-filter captures particles such as mold and spores, reducing the load on downstream filtration.
H11 grade HEPA filtration supports removal of fine airborne pollutants for cleaner fresh-air supply.
Activated carbon helps absorb formaldehyde, benzene, radon and other harmful chemical pollutants.
Negative ion filtration attaches to positively charged particles such as dust, bacteria, pollen and smoke.
The cabinet can be mounted vertically, horizontally or inverted depending on project layout.

Model performance can be reviewed visually before airflow selection and project matching.
Motors: External rotor motors, IP44, class B, with ball bearings and thermal protection. Electrical supply: single phase 230V-50Hz. Working temperature from -20ºC to +40ºC.
On request: Versions protected against corrosion by epoxy paint coating are available for projects that require stronger environmental resistance.
Low noise level: Acoustic insulation of 7 mm thickness flame-retardant melamine foam helps reduce noise level significantly.
Easy to mount: All models are supplied with four mounting feet to support ceiling, wall or floor mounting. Installation can be vertical, horizontal or inverted.
2 Filters 4 Purification: The filtration set combines washable primary filtration with multiple downstream purification layers for finer project air treatment.
Primary Effect Filtering Net: Filters larger particulate matter and can be washed for repeated maintenance cycles.
Activated Carbon Filter: Helps decompose formaldehyde, TVOCs and other harmful gases commonly found in indoor project environments.
Negative Silver Ion Effect Filter: Supports sterilization and disinfection performance as part of the multi-stage fresh-air treatment path.
H11 Grade HEPA Filter Net: Filters PM2.5, viruses, allergens and other fine airborne contaminants before supply air enters the room.
Fresh-air ventilation for rooms and projects that need filtered supply air, practical duct connection and quieter operation.
Homes and apartments that need filtered fresh air with quieter daily operation.
Offices, reception rooms and shared spaces requiring filtered ventilation support.
Light project spaces where cabinet mounting, duct connection and stable airflow matter.
We eliminate procurement and installation risks through rigorous factory verification and straightforward B2B warranty support.
Every batch undergoes strict functional and dimensional routing tests, including filter fit, external rotor motor operation, acoustic insulation assembly, and mounting orientation verification. We ensure that every single unit arrives at your project site fully functional and ready for flawless installation.
We stand firmly behind our manufacturing craftsmanship. In the rare event of any material defect or mechanical failure under standard project operations, KCVENTS provides a straightforward, hassle-free hardware replacement service to secure your timeline.
As a global manufacturer of HVAC and ventilation equipment, KCVENTS is dedicated to providing flexible customization services and robust long-term supply chain warranty terms for contractors, brands, and wholesalers.
We support full private labeling (OEM) and custom housing finishes. Our ODM engineering covers custom chassis modifications, specialized airflow curves, and regional electrical standards (e.g., 110V/60Hz, 24V variable frequency).
For large-scale HVAC and green building deployments, we offer structured MOQ tiers, staged shipping contracts, and agile multi-batch delivery aligned with your construction timeline. Technical submittals and parameter validation are included.
Motors enjoy an extended warranty of up to 3 to 5 years, backed by a comprehensive 1-year full system warranty. Bulk orders are eligible for a dedicated percentage of maintenance spares along with 1-on-1 remote engineering support.
