System Overview<\/span><\/h2>\n
\n

DPT-J Fresh Air Ventilation is designed for fresh-air projects that require multi-stage filtration, stable air delivery and flexible cabinet-style installation.<\/p>\n

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.<\/p>\n <\/div>\n <\/section>\n\n

\n

Core Engineering Features<\/span><\/h2>\n

Built for multi-stage fresh-air purification, DPT-J combines filtration, cabinet mounting flexibility and low-noise construction for B2B project use.<\/p>\n

\n \n
\n
METAL FILTER<\/div>\n

Large Particle Protection<\/h3>\n

The metal filter removes large particles, small insects and pollen before air reaches the finer filter stages.<\/p>\n <\/div>\n\n

\n
PRE-FILTER<\/div>\n

Up to 90% Pre-Filtration<\/h3>\n

The pre-filter captures particles such as mold and spores, reducing the load on downstream filtration.<\/p>\n <\/div>\n\n

\n
H11 HEPA<\/div>\n

Up to 95% Fine Filtration<\/h3>\n

H11 grade HEPA filtration supports removal of fine airborne pollutants for cleaner fresh-air supply.<\/p>\n <\/div>\n\n

\n
CARBON FILTER<\/div>\n

Chemical Odor Absorption<\/h3>\n

Activated carbon helps absorb formaldehyde, benzene, radon and other harmful chemical pollutants.<\/p>\n <\/div>\n\n

\n
NEGATIVE ION<\/div>\n

Allergen Particle Capture<\/h3>\n

Negative ion filtration attaches to positively charged particles such as dust, bacteria, pollen and smoke.<\/p>\n <\/div>\n\n

\n
EASY MOUNT<\/div>\n

Flexible Installation Position<\/h3>\n

The cabinet can be mounted vertically, horizontally or inverted depending on project layout.<\/p>\n <\/div>\n <\/div>\n <\/section>\n\n

Filtration & Installation Notes<\/span><\/h2>\n
\n

Motors:<\/strong> External rotor motors, IP44, class B, with ball bearings and thermal protection. Electrical supply: single phase 230V-50Hz. Working temperature from -20\u00baC to +40\u00baC.<\/p>\n

On request:<\/strong> Versions protected against corrosion by epoxy paint coating are available for projects that require stronger environmental resistance.<\/p>\n

Low noise level:<\/strong> Acoustic insulation of 7 mm thickness flame-retardant melamine foam helps reduce noise level significantly.<\/p>\n

Easy to mount:<\/strong> All models are supplied with four mounting feet to support ceiling, wall or floor mounting. Installation can be vertical, horizontal or inverted.<\/p>\n

2 Filters 4 Purification:<\/strong> The filtration set combines washable primary filtration with multiple downstream purification layers for finer project air treatment.<\/p>\n

Primary Effect Filtering Net:<\/strong> Filters larger particulate matter and can be washed for repeated maintenance cycles.<\/p>\n

Activated Carbon Filter:<\/strong> Helps decompose formaldehyde, TVOCs and other harmful gases commonly found in indoor project environments.<\/p>\n

Negative Silver Ion Effect Filter:<\/strong> Supports sterilization and disinfection performance as part of the multi-stage fresh-air treatment path.<\/p>\n

H11 Grade HEPA Filter Net:<\/strong> Filters PM2.5, viruses, allergens and other fine airborne contaminants before supply air enters the room.<\/p>\n <\/div>\n <\/section>\n\n
