Shrijee Wind Ventilator Vs. Conventional Ventilator
Shrijee Wind Ventilator
|Shrijee wind ventilators are suitable for any place where natural wind is available.
|Suitable for only those places where electricity is available.
|Operates on natural wind available
|Requires electrical energy at rated voltage.
|Can operate at varying velocities. Any fluctuation in wind velocity affects air discharge marginally without damage to ventilator components.
|Requires rated electricity. Any fluctuation in voltage & amperage may damage the components of electrically operated system.
|Assured operation for 24 hours a day, 365 days a year.
|Can operate only when power supply is available.
|Do not require any wiring, switching and person to operate.
|Require necessary wiring, switchboards, and persons to operate.
|No maintenance costs, as there are no armatures / field coils / switches.
|Maintenance required due to the presence of armature, field coil, switches, and carbon brushes.
|No electricity bills & installation of Shrijee wind ventilators are free of running costs.
|Increasing cost of electricity makes electrically operated ventilator a costly proposition.
|There are no accident hazards. Suitable for usage in areas sensitive to accidental hazards.
|Prone to accidents like electrical short circuits & shocks. Accidents could be fatal & losses due to fire could be catastrophic.
|Operation is free of rodent menace
|Rodents can damage electrical wiring resulting in stoppage of ventilation systems.
