⚡ How Much Power VSD Air Compressor Saves (With Calculation)

Electricity cost is the biggest expense in compressed air systems. A VSD (Variable Speed Drive) compressor can reduce power consumption significantly.

⚙️ What is VSD?

A VSD compressor adjusts motor speed based on air demand instead of running at full load continuously.

📊 Example Calculation (20 HP Compressor)

Let’s compare:

Compressor: 20 HP (≈ 15 kW)

Operating: 10 hours/day

Electricity cost: ₹8/unit

🔹 Without VSD (Fixed Speed)

Runs full load always

Power consumption = 15 kW × 10 hrs = 150 units/day

🔹 With VSD

Average load = 60–70%

Power consumption ≈ 9–10 kW

👉 Daily usage = 100 units/day (approx)

💰 Savings Calculation

Daily saving = 50 units

Monthly saving = 50 × 30 = 1500 units

Monthly cost saving = ₹12,000

Yearly saving = ₹1.4 to ₹1.8 lakhs
