Por qué los filtros HVAC estándar fallan en el mar
Marine environments are among the most demanding for air filtration equipment. The combination of salt spray, constant high humidity, vibration, and corrosive sea air destroys standard HVAC filters in weeks — or days in open-ocean conditions.
| Failure Mode | Standard HVAC Filter | Nantong Deli Marine Filter |
|---|---|---|
| Frame material | Cardboard — absorbs moisture, collapses | Rigid PP / ABS / Stainless steel |
| Salt spray resistance | None — corrodes metal components | Fully salt-spray tested media and frame |
| Humidity tolerance | Degrades above 80% RH | Rated to 100% RH continuous |
| Vibration resistance | Media can shift and tear | Reinforced media bonding for marine vibration |
| Antimicrobial | Standard — mold grows rapidly in wet conditions | Silver ion treatment available |
| Service life (marine env.) | Days to weeks | 30–90 days (application-dependent) |

Preguntas frecuentes
¿Qué hace que un filtro sea adecuado para la ventilación marina?
Marine ventilation filters require corrosion-resistant frames (stainless steel, PP, or ABS — never cardboard or plain steel), media that retains structural integrity at 100% RH, salt-spray resistance, and vibration-resistant bonding. Standard HVAC filters fail rapidly in marine environments.
¿Qué aplicaciones utilizan filtros de ventilación marina?
Yacht and recreational boat HVAC, commercial vessel engine room ventilation, offshore oil and gas platform HVAC, naval vessel air handling units, port terminal HVAC, and coastal industrial facilities.
¿Puede Nantong Deli fabricar filtros de ventilación marina en tamaños personalizados?
Yes — any dimension, any frame material, any media grade, from CAD drawings or a sample OEM filter. Free samples within 7 days of dimension confirmation.
¿Qué clasificación MERV se recomienda para HVAC marino?
MERV 8–11 (F5–F6) for cabin HVAC; G3–G4 for engine room pre-filters; MERV 13 (F7) for offshore control rooms. We help match the right grade to your airflow and contamination requirements.
¿Cuál es la cantidad mínima de pedido?
200 units for custom-dimension production. Sample orders of 20–50 units available for engineering evaluation. Contact amanda@ntdeli.top.

¿Cuál es la correspondencia EN 779 e ISO 16890 para las clases EU de filtros marinos?
EN 779 fue la norma europea para clasificación de filtros de ventilación general (G1–F9), sustituida por ISO 16890 en 2016. Muchas especificaciones OEM aún referencian clases EN 779. Los filtros marinos de Nantong Deli pueden especificarse con ambas: EN 779 G3–F9 o ISO 16890 ePM10–ePM1.
