01 · Vent Master commercial ventilation
Specialty restaurant ventilation, UV-light and water-wash leadership.
Vent Master is the independent US commercial kitchen ventilation manufacturer focused on the high-end advanced ventilation niche. Where CaptiveAire and Greenheck dominate volume on standard restaurant exhaust, Vent Master concentrates on three premium technology categories that matter for high-grease-load operations and emissions-regulated jurisdictions:
- UV-light grease management. UV-C bulbs in the hood plenum break down grease vapor before it accumulates on filter surfaces and ductwork.
- Water-wash self-cleaning hoods. Built-in spray manifold runs nightly cleaning cycles to flush grease downward into drain.
- Pollution Control Units (PCU). Downstream emissions filtration for restaurants in CARB-regulated zones near residential.
We see Vent Master most often in high-end LA-area restaurants: steakhouses (heavy grease from char-grilling), 24-hour operations, mixed-use buildings in West Hollywood and Beverly Hills where exhaust emissions face stricter regulation, and restaurants near residential zones in Pacific Palisades and Newport Coast.
$120 commercial diagnostic, waived with repair. BHGS Licensed #A49573, EPA 608 Universal certified (#1346255700410), C-20 HVAC scope. 90-day warranty. Same-day across LA, OC, Ventura. See parent: commercial kitchen exhaust hood repair pillar.
02 · UV-light grease management
UV-C bulbs break grease vapor before it accumulates.
The technology: UV-C light at 254 nanometers wavelength breaks the molecular bonds in airborne grease vapor as it passes through the hood plenum. The grease oxidizes into smaller, less-sticky particles that pass through filtration and ductwork without accumulating.
Operational benefits documented in field service:
- Cleaning frequency reduction. Operations that previously needed quarterly grease cleaning (NFPA 96 schedule for moderate-volume) can often shift to semi-annual or annual cleaning with healthy UV system.
- Reduced grease fire risk. Less grease accumulation in ductwork means lower fire load along the exhaust path.
- Lower exhaust fan strain. Cleaner airflow path, lower static pressure drop, longer fan motor life.
- Health Department documentation easier. Cleaner hoods photograph better at routine inspection.
UV bulbs are wear parts. Standard restaurant operating hours produce 4,000 to 5,000 hours per year of UV runtime; bulbs typically replaced at 8,000 to 12,000 hours, which is every 9 to 14 months. Bulb pricing $80 to $180 per bulb depending on model; multi-bulb hoods $400 to $780 full set.
Service note: UV bulbs are NOT user-serviceable parts. Direct UV-C exposure causes eye damage. We replace under safe-handling protocols. UV bulb breakage releases mercury, which we contain and dispose of per EPA guidelines.
03 · Water-wash self-cleaning hoods
For high-grease-load operations only.
Water-wash hoods incorporate a built-in cleaning cycle. A spray manifold inside the plenum runs hot water plus food-safe detergent solution at scheduled intervals (typically nightly during downtime) to flush grease accumulation downward into a built-in drain.
The economic case for water-wash:
- High-grease operations (steakhouses, char-grilling, 24-hour kitchens). Manual cleaning frequency would be every 2 to 4 weeks at significant labor cost. Water-wash automates this.
- Multi-shift operations where downtime is limited. Manual cleaning requires hours of kitchen downtime; water-wash runs during the natural close cycle.
- Operations with consistent grease load. Water-wash performs best when grease accumulation is predictable; intermittent heavy bursts can overwhelm the cleaning cycle.
The case against water-wash:
- Moderate-volume operations. Manual cleaning at quarterly NFPA cadence is cheaper than water-wash maintenance complexity.
- Low-grease cooking (sandwich shops, salad-focused, beverage-heavy). Not enough grease to justify the system.
- Plumbing-constrained installations. Water-wash needs reliable hot water supply plus drain; not always feasible in retrofit scenarios.
Common water-wash service items: spray nozzle clogging from mineral scale (LADWP hard water primary), detergent dispenser pump replacement, drain blockage from grease accumulation in the drain line, and timer or control board replacement.
04 · Pollution Control Units (PCU)
Required in CARB-regulated emissions zones.
Pollution Control Units are downstream filtration assemblies that remove additional grease, smoke, and odor from exhaust air before it leaves the building. PCU adoption is mandated in some Los Angeles County jurisdictions for restaurants near residential zones, in mixed-use buildings, and in proximity-sensitive areas under California Air Resources Board (CARB) emissions guidelines.
Common PCU technologies:
- Mist collectors. Coalesce grease aerosol particles into larger droplets that drain off rather than escape.
- Electrostatic precipitators (ESP). Charge airborne particles, then trap them on oppositely-charged collection plates.
- Carbon odor filters. Activated charcoal media absorbs odor compounds.
- HEPA-grade filtration. Final particle capture before exhaust to atmosphere.
PCU service involves filter replacement (varies by media type), mist collector drain cleaning, ESP plate cleaning and high-voltage power supply check, and carbon media replacement on schedule. PCU service runs $440 to $1,200 per visit depending on configuration.
Geographic concentration of PCU installations in our service area:
- West Hollywood mixed-use buildings. Restaurants on Sunset, Santa Monica Blvd with residential above.
- Beverly Hills core commercial. Restaurants near residential blocks.
- Pacific Palisades, Brentwood. Restaurants near residential cliffs.
- Newport Beach, Newport Coast. Restaurants with ocean view residential adjacency.

07 · FAQ
Vent Master service, common questions.
What is a Vent Master UV-light hood and how does it work?
UV-C light installed in the hood plenum breaks down grease vapor before it accumulates on filter surfaces and ductwork. Effect: extends time between deep grease cleanings (often from quarterly to semi-annual on moderate-volume kitchens), reduces grease fire risk in the duct path, and lowers exhaust fan strain because of cleaner airflow. UV bulbs are wear parts (8,000 to 12,000 operating hours typical), replaced as part of routine PM. Bulb replacement runs $80 to $180 per bulb depending on model; multi-bulb hoods $400 to $780 for full set.
What's a water-wash hood and is it worth the complexity?
Water-wash hoods incorporate a built-in cleaning cycle: a spray manifold inside the plenum runs hot water plus detergent solution at scheduled intervals (typically nightly during downtime) to flush grease accumulation downward into a drain. Reduces manual cleaning frequency. Worth it on high-volume operations (steakhouses, char-grilling, 24-hour kitchens) where grease load is heavy enough that manual cleaning frequency would be every 2 to 4 weeks. Not worth the complexity on moderate-volume or low-grease kitchens. We service both Vent Master water-wash and standard pressure systems.
What's a Pollution Control Unit (PCU) on a Vent Master hood?
PCU is a downstream filtration assembly that removes additional grease, smoke, and odor from exhaust air before it leaves the building. Required in some Los Angeles County jurisdictions for restaurants close to residential zones (notably parts of West Hollywood, Pacific Palisades, Beverly Hills mixed-use blocks) where exhaust discharge is regulated under California Air Resources Board guidelines. PCU service involves filter replacement, mist-collector cleaning, and electrostatic precipitator maintenance. $440 to $1,200 per service visit depending on PCU configuration.
Is Vent Master independent or part of a larger group?
Vent Master is an independent commercial ventilation manufacturer focused on the restaurant ventilation niche, particularly UV-light grease management and water-wash systems. The company is privately held and US-manufactured. Parts pipeline runs through their authorized distribution network with 5 to 10 day standard sourcing on common parts; specialty UV bulbs and PCU filter media occasionally require longer order times.
How much does UV-light bulb replacement cost annually?
Depends on hood length and UV configuration. Single 4-foot hood with one UV bulb: bulb costs $80 to $180, replaced every 9 to 14 months on standard restaurant operating hours. Larger 8-foot or 10-foot hood with multi-bulb arrays: $400 to $780 full bulb set, same replacement interval. Annual budget $80 to $780 for UV maintenance depending on installation. Compare against grease cleaning frequency reduction: many operators save more on cleaning service than they spend on UV replacements.
Do you service Vent Master under annual contract?
Yes. Annual contract includes UV bulb replacement (1 to 2 visits per year), water-wash spray manifold inspection, PCU filter media replacement when applicable, and NFPA 96 inspection documentation. Contract pricing $980 to $2,400 annual depending on hood configuration and grease load. Larger steakhouse-tier installations with multi-zone water-wash plus PCU run higher. We document every visit for Fire Marshal records.
