15 high-fidelity calculators providing foundational engineering insights for optimal fan system design, maintenance planning, and energy efficiency verification.
Facilitates instantaneous conversion of core fan performance units: Airflow (m³/h ↔ CFM), Static Pressure (Pa ↔ inAq), and acoustic levels (dB), ensuring immediate global specification compatibility.
Access Conversion UtilitySolves for unknown electrical parameters (V, A, or W) across DC, AC Single-Phase, and AC Three-Phase systems. Crucial for motor sizing, thermal load assessment, and hourly cost estimation (USD).
Access Power CalculatorPredicts the resulting fan performance (Flow Q, Pressure P, Power W) based on alterations to the impeller diameter (mm), utilizing the geometrical fan affinity laws for model optimization.
Access Scaling ModelQuantifies the theoretical energy reduction (USD) achieved by implementing Variable Frequency Drives (VFD) for fan speed (RPM) modulation, leveraging the cubic power law for fast ROI projection.
Access ROI CalculatorProvides a component-based analysis framework to accurately determine the total required Static Pressure (Pa) by summing losses from ducts, filters, coils, and fittings within the air handling system.
Access Pressure EstimatorCalculates the dimensionless Specific Speed (Ns) and provides guidance on the optimal fan type (e.g., Axial vs. Centrifugal) required for peak energy-efficient operation at a defined duty point (m³/h, Pa, RPM).
Access Ns OptimizerEstimates the fan's acoustic output (Sound Power Level Lw in dB) and isolates broadband and tonal noise components. Indispensable for compliance with environmental and occupational noise standards.
Access Acoustic PredictorModels the resultant performance envelope and intersection point (m³/h and Pa) when two or more fans are employed in parallel (flow augmentation) or series (pressure boost) configurations.
Access Combination ModelerComputes the irreversible pressure drop (Pa) due to surface friction in straight circular or rectangular ducts, using flow rate (m³/h), dimensional inputs, and material roughness factors.
Access Friction CalculatorAutomatically adjusts rated fan performance (Q, P, W) to compensate for density variations caused by changes in altitude, ambient temperature (°C), or humidity, ensuring accurate field operation data.
Access Density CorrectorApplies the fundamental Fan Affinity Laws to predict changes in flow, pressure, and power consumption exclusively due to variations in operational speed (RPM). Critical for fan system commissioning.
Access RPM Affinity ToolCalculates the ISO standard bearing fatigue life (Hours) and key characteristic fault frequencies (BPFI, BPFO, BSF, FTF in Hz). Essential for condition monitoring and proactive maintenance planning.
Access Reliability PredictorQuantifies the Total Cost of Ownership (TCO) of a fan or motor system over its project lifetime by calculating purchase cost, total energy cost (P_input), and maintenance costs (USD).
Access LCC/TCO AnalyzerDetermines the minimal standard motor size (HP/kW) and estimates efficiency (ηMotor) and electrical input power (P_input) based on the required fan shaft mechanical power (Pmech).
Access Motor Sizing ToolFacilitates instantaneous conversion between common engineering units for logistics and installation planning, covering length (m ↔ ft ↔ in) and mass (kg ↔ lb ↔ oz).
