Why Double Inlet Double Width (DIDW) Fans are the Benchmark for High-Volume, Mid-Static Pressure Industrial Air Movement.
Double Inlet Double Width (DIDW) centrifugal blowers represent a vital fluid-dynamics solution for industrial applications requiring substantial volumetric airflow (CFM or m³/h) combined with modest to high static resistance (Pascal or inches W.G.). Unlike single-inlet blowers—which draw air from a single side of the scroll housing—a double inlet centrifugal blower features air suction ports on both lateral faces of the volute. This dual-suction design doubles the inlet throat area without proportionally increasing the overall rotor wheel diameter.
By splitting incoming mass flow across two balanced inlet cones, double inlet blowers halve the axial entrance velocity. This significantly minimizes turbulence at the blade leading edges, yielding up to 18% higher mechanical efficiency compared to oversized single-inlet units.
We supply both Forward-Curved (FC) multi-vane impellers for quiet operation in compact air handling units, and Backward-Curved (BC) impellers for non-overloading horsepower characteristics in heavy continuous-duty filtration and industrial drying processes.
Direct-drive external rotor motor blowers offer extremely compact footprints and zero maintenance, whereas belt-driven double inlet units provide flexible speed ratios via adjustable pulleys for variable airflow commissioning.
| Blower Architecture | Airflow Capacity (CFM) | Static Pressure Range | Acoustic Profile | Motor Drive Type | Primary Industrial Utility |
|---|---|---|---|---|---|
| DIDW Forward Curved (FC) | 800 – 18,000 CFM | 100 Pa – 750 Pa | Low Noise (62–74 dBA) | Direct / Belt Drive | Commercial HVAC, Cleanroom AHUs, Evaporative Coolers |
| DIDW Backward Curved (BC) | 1,500 – 35,000 CFM | 400 Pa – 2,200 Pa | Medium (68–82 dBA) | Direct / Coupling / Belt | Agricultural Drying, Dust Collection, Industrial Ovens |
| External Rotor DIDW | 400 – 4,500 CFM | 50 Pa – 500 Pa | Ultra-Quiet (54–68 dBA) | Direct Integrated EC/AC | Precision Medical Equipment, Telecommunication Racks |
Costa Rica’s unique geography, microclimates, and rapidly expanding manufacturing base demand air movement equipment engineered specifically for high humidity, tropical coastal atmosphere, and stringent energy efficiency goals.
In key coffee-growing regions such as Tarrazú, Heredia, and the Central Valley, double inlet centrifugal blowers are indispensable for green coffee bean dehumidification and post-harvest drying. Processing facilities require continuous-duty blowers capable of forcing heated air through dense beds of parchment coffee against high static backpressure.
Localization Requirement: Heavy-duty motor windings with Class H insulation and moisture-proof varnish coating to resist ambient relative humidity levels exceeding 90% during the harvest season (November to March).
Costa Rica is a Latin American powerhouse for medical device manufacturing, concentrated heavily in industrial parks like El Coyol Free Zone (Alajuela) and Parque Empresarial Forum. Cleanrooms require absolute air containment and constant air change rates (ACH).
Localization Requirement: Double inlet centrifugal blowers equipped with high-efficiency backward-curved impellers and EC (Electronically Commutated) motors. These units integrate seamlessly with HEPA filtration banks, maintaining laminar airflow with minimal heat generation inside cleanroom air handlers.
From luxury eco-lodges in Guanacaste and Manuel Antonio to commercial centers in San José, HVAC infrastructure must run non-stop to manage tropical heat and moisture while maintaining quiet guest spaces.
Localization Requirement: Ultra-quiet direct-drive double inlet blowers housed in electro-galvanized or aluminum anti-corrosion casings. Specialized anti-corrosion marine epoxy treatments are applied to protect metal casings against salty ocean mist in Pacific and Caribbean coastal installations (Puerto Limón & Puntarenas).
As one of the world's leading exporters of fresh pineapples and bananas, Costa Rica operates extensive cold storage facilities near major transit hubs like Puerto Limón and Moín. Refrigeration blowers must maintain forced-air pre-cooling to rapidly remove field heat from freshly harvested fruit.
Localization Requirement: IP55-rated water-resistant double inlet blowers with low-temperature synthetic lubrication bearings engineered to prevent condensation ingress inside blast-freezing tunnels and cold storage vaults.
Costa Rica is a global model for environmental sustainability, operating on nearly 99% renewable electricity (hydroelectric, geothermal, and wind power). Under the national Plan Nacional de Descarbonización (2018–2050), industrial enterprises across the country are facing strict mandates to replace inefficient electrical equipment with high-efficiency motor-driven systems (EMDS).
Unlike South American nations operating on 50Hz, Costa Rica runs strictly on a 60Hz frequency standard (120V/240V single-phase, 208V/230V/460V 3-phase). Installing imported 50Hz blowers without motor re-winding causes severe overheating, reduced airflow velocity, and premature stator burnout. Our blowers are specifically wound and balanced for 60Hz magnetic field speeds.
Industrial procurement managers in Costa Rica prioritize compliance with guidelines set by the Instituto Costarricense de Normas Técnicas (INTECO) and the Ministerio de Ambiente y Energía (MINAE). Our IE3 premium efficiency motors and EC blowers directly support factory energy audits, slashing electrical demand charges (kW/kWh tariffs).
Continuous exposure to relative humidity ranging between 80% and 98% accelerates electrical breakdown. All our double inlet centrifugal blowers exported to Costa Rica feature vacuum-pressure impregnated (VPI) copper windings, sealed stainless steel ball bearings, and powder-coated steel scroll housings.
