Industry-First IQV™ Technology

IQV™ technology was first developed and validated in high-precision industrial ventilation environments — settings where particle capture accuracy, airflow stability, and contamination containment are mission-critical requirements, not consumer conveniences.
The core engineering principles — inclined quad-vortex cyclone formation, pressurized narrow-slot intake, and multi-layer containment airflow — were refined in industrial applications before being adapted for residential kitchen use.

This origin matters because it means IQV's performance claims are not based on consumer product testing alone. The underlying fluid dynamics have been stress-tested in demanding industrial conditions. What Arspura has done is translate that industrial-grade precision into a home kitchen ventilation system that over one million families worldwide now use daily.

IQV™ (Inclined Quad-Vortex) is Arspura's patented Dynamic Particle Capture Technology. When activated, it generates four counter-rotating low-pressure cyclones directly above your cookware, locking smoke, grease, odors, and PM2.5 particles at the source — before they rise, spread, or escape into your living space.
Here's the full three-stage process that makes Arspura's kitchen ventilation system fundamentally different:

Stage 1 — Source Locking

The narrow, elongated air intake slot generates ultra-high airspeed. Combined with side smoke-blocking panels, this creates four counter-rotating low-pressure vortices directly above the cooktop surface. Cooking pollutants — including invisible PM2.5 fine particles — are drawn into these cyclones and contained before they can rise.

Stage 2 — High-Speed Extraction

The 250W BLDC motor drives airflow at 13–16 m/s through the pressurized intake slot, instantly pulling captured pollutants through the exhaust duct and out of your kitchen. This capture velocity is 3–5× faster than the 3–5 m/s intake speed of conventional kitchen exhaust hoods

Stage 3 — Anti-Escape Air Curtain

Two upper air outlets project a precision air curtain that forms a sealed barrier between the cooking zone and the room. Any residual fumes that escape the primary cyclone field are intercepted here — preventing them from drifting into open-plan living areas.

The result: a sealed "anti-leakage triangle zone" that keeps your kitchen ventilation effective even during intense wok cooking, even in open-plan kitchens with crosswinds.

CFM (Cubic Feet per Minute) measures the total volume of air a range hood moves per minute. A common rule of thumb: you need approximately 100 CFM per 10,000 BTU of cooktop output. A 40,000 BTU gas stove would need at least 400 CFM.

However, CFM is a deeply misleading metric for real-world kitchen ventilation performance. Here's why:

● No global standard. CFM is measured at zero static pressure in lab conditions — not in your actual kitchen with ductwork, bends, and backpressure. Real-world performance is always lower.

● Decay with distance. As the distance between the hood and the cooktop increases, suction velocity drops dramatically.

● Duct resistance compounds the loss. Every meter of ductwork, every 90° bend, and every narrow flue opening reduces effective airflow.

● Volume ≠ capture. Opening a window provides enormous "ventilation volume" — yet cooking odors and PM2.5 still fill the room.

Why Arspura focuses on capture velocity instead:

The P1 IQV concentrates airflow through a narrow pressurized intake slot, achieving 13–16 m/s at the capture zone — directly above your cookware. This is 3–5× the velocity of conventional cooktop vent hoods.

Think of it this way: a fire hose and a garden sprinkler can move the same volume of water per minute — but only one of them can knock something down.

Most kitchen exhaust hoods handle visible smoke — the large particles you can see. Odors are a different challenge entirely. Odor molecules are microscopic, travel with airflow, and cling to surfaces, fabrics, and hair long after cooking ends.

IQV technology addresses odors through three mechanisms working simultaneously:

1. Source containment — The four cyclones form a low-pressure zone directly above the cookware, preventing odor molecules from rising into the room in the first place.

2. High-velocity extraction — At 13 m/s, airflow is fast enough to capture and discharge odor-carrying particles before they diffuse into the kitchen atmosphere.

3. Anti-escape air curtain — The upper air curtain creates a physical barrier between the cooking zone and the open room, intercepting any odor molecules that escape the primary capture field.

The result: 95% odor reduction rate — verified under standard testing conditions. Whether you're stir-frying chili, cooking fish, or boiling strong-smelling broths, no lingering odors on clothes, hair, or soft furnishings.

The tempered glass smoke-blocking panels on either side of the hood serve a precise aerodynamic function — they are not decorative.
By forming physical walls on both sides of the cooking zone, the panels:
●Contain lateral spread — preventing crosswinds or body movement from disrupting the IQV capture field
●Extend the effective capture zone — pushing the low-pressure cyclone area closer to the cookware surface
●Reinforce the anti-leakage triangle — working together with the upper air curtain to create a sealed three-dimensional containment zone
This is why the P1 IQV performs reliably in open kitchens where traditional cooking ventilation systems fail — the panels neutralize the crosswinds and foot-traffic disturbances that cause conventional hoods to leak.
⚠️ Tempered glass has an extremely small probability of spontaneous breakage due to the tempering process. In the event of non-misuse spontaneous breakage, Arspura will replace the component free of charge. Avoid striking the glass with cookware or hard objects, especially at the corners.

PM2.5 refers to airborne fine particles with a diameter of 2.5 microns or less — about 1/30th the width of a human hair. These particles are generated in large quantities during cooking, especially high-heat stir-frying, grilling, and deep-frying.
They are dangerous because:
●They bypass the body's natural defenses — too small to be filtered by nasal passages or upper airways
●They penetrate deep into lung tissue, increasing long-term risk of respiratory disease and cardiovascular conditions
●They cause skin irritation and accelerate premature aging with repeated exposure
●They worsen pre-existing conditions such as asthma, COPD, and bronchitis
●They cling to clothing, hair, and soft furnishings, leaving persistent odors and surface contamination
This is why a home kitchen ventilation system that only removes visible smoke is insufficient. Visible smoke particles are large — PM2.5 is what remains invisible in the air and poses the real health risk.

Traditional range hoods use mesh filters to physically intercept grease droplets as air passes through. This works — but filters clog, require regular cleaning or replacement, and become a fire hazard when saturated with grease.
Arspura eliminates the filter entirely through centrifugal separation:
1.The high-speed BLDC motor and pressurized intake slot generate powerful airflow at 13 m/s
2.This creates intense centrifugal force as air spins through the system
3.Grease droplets — which are heavier than air — are flung outward by centrifugal force and directed into the oil cup
4.Clean air continues through the exhaust duct
The principle is identical to a washing machine's spin-dry cycle: centrifugal force separates heavier particles from lighter ones without any physical barrier needed.
The role of the Volute Housing Assembly: Arspura's reinforced volute housing is a structurally optimized chamber that guides high-speed airflow in a precisely controlled spiral path — amplifying the centrifugal force that separates grease droplets from the airstream and directs them into the oil cup. Without a well-engineered volute, high-speed airflow becomes turbulent, reducing separation efficiency and increasing operational noise. The optimized chamber geometry ensures that centrifugal separation remains consistent across all speed levels, from everyday simmering to full Turbo mode.
Result: lifetime filter-free design. Zero filter replacement costs. Zero monthly maintenance. 85% grease separation rate verified under standard testing.
