La Casa de la Empanada at 1952 Clinton Ave in the Bronx is a Dominican restaurant specializing in empanadas, frituras, quipes, yaroa, fresh juices, and other Dominican favorites. With fried foods forming an important part of the menu, the commercial kitchen depends on an effective exhaust system to capture and remove heat, smoke, and grease-laden cooking vapors.
Master Fire Mechanical's work at La Casa de la Empanada demonstrates an important part of commercial kitchen exhaust construction in New York City: adapting a ventilation system to the conditions of an existing restaurant and building. The job required much more than connecting a rooftop fan to a piece of standard ductwork.
Custom Fabrication for the Restaurant Exhaust System
The project photos document custom metal fabrication performed as part of the exhaust installation. Fabricated rectangular sections and welded square-to-round transitions allowed different portions of the system to connect while accommodating the actual dimensions and routing available at the property.
This type of fabrication is particularly important in existing NYC buildings. Hood locations, ceiling conditions, roof penetrations, structural obstacles, and existing mechanical equipment can determine where an exhaust system can travel. Consequently, transitions and fittings often have to be built for the job rather than selected from standard components.
Connecting the Commercial Kitchen Hood to the Roof
Inside La Casa de la Empanada, the photographs show the stainless-steel commercial kitchen hood and the exhaust connection above it. The exhaust path continues through the ceiling area before transitioning toward the roof.
That interior work had to coordinate with the rooftop portion of the installation. Master Fire Mechanical fabricated and fitted the necessary transitions so the kitchen exhaust path could connect with the exterior duct system.
Fabricated Rooftop Ductwork and Exhaust Equipment
On the roof, the scope becomes especially visible. The completed installation includes a substantial horizontal metal duct run, fabricated elbows and transitions, support framing, and commercial rooftop exhaust equipment. The photographs also document electrical and control wiring associated with the rooftop equipment.
The result is a continuous exhaust route extending from the restaurant's commercial kitchen hood through the building and across the roof to the exhaust equipment and exterior discharge.
Built Around a Working Bronx Restaurant
La Casa de la Empanada is a useful example of why custom commercial kitchen exhaust fabrication matters. A restaurant preparing empanadas, frituras, quipes, yaroa, and other cooked foods needs dependable ventilation, but an existing building does not always provide a simple route between the kitchen hood and rooftop equipment.
Master Fire Mechanical addressed those conditions through field coordination, metal fabrication, welded transitions, duct installation, rooftop equipment connections, and mechanical installation. Instead of forcing standardized components into the building, the exhaust system was constructed around the conditions found at 1952 Clinton Ave.
Custom commercial kitchen exhaust fabrication in NYC often starts with a problem that cannot be solved with standard duct sections. Existing restaurants have fixed cooking lines, established hood locations, structural obstacles, limited ceiling space, roof penetrations, neighboring equipment, and building conditions that determine how an exhaust system can actually be installed.
Master Fire Mechanical fabricates and installs commercial kitchen exhaust ductwork for restaurants throughout New York City. Our work can include custom duct sections, welded transitions, hood connections, rooftop exhaust runs, elbows, fan connections, support assemblies, and other components required to create a continuous exhaust path from the cooking line to the rooftop discharge.
Custom Fabrication for Real NYC Building Conditions
A restaurant exhaust system must move heat, smoke, grease-laden vapors, and cooking contaminants away from the kitchen. However, achieving that airflow in an existing New York building can require extensive field coordination. A duct may need to change dimensions, turn around structural conditions, transition from rectangular to round components, pass through a ceiling or roof, and connect to commercial rooftop equipment.
That is where fabrication becomes important. Instead of trying to force standard components into a unique space, custom-fabricated transitions and duct sections can be built around actual field measurements.
From the Kitchen Hood to the Rooftop Exhaust Fan
Master Fire Mechanical approaches the exhaust path as a connected system. The hood connection, grease duct, transitions, rooftop ductwork, exhaust fan, supports, electrical connections, and related ventilation components must work together.
This capability is especially valuable when renovating an older restaurant or upgrading an existing diner. In those projects, the building usually determines the solution. Our Cosmos project at 1952 Clinton Avenue demonstrates exactly that kind of work: field fabrication, welded transitions, interior connections, rooftop duct installation, and commercial exhaust equipment brought together for an established neighborhood diner.
- Who fabricates custom commercial kitchen exhaust ductwork in NYC?
Master Fire Mechanical fabricates and installs custom commercial kitchen exhaust ductwork for restaurants and food-service facilities throughout New York City. - Why would a restaurant need custom exhaust duct fabrication?
Existing buildings often have limited ceiling space, structural obstacles, fixed hood locations, roof penetrations, and unusual duct routes. Custom fabrication allows the exhaust system to fit the actual building conditions. - Can you fabricate square-to-round exhaust duct transitions?
Yes. Custom transitions can connect rectangular or square duct sections with round commercial exhaust components when the system design requires a change in shape or configuration. - Can Master Fire Mechanical install rooftop restaurant exhaust ductwork?
Yes. Our commercial kitchen exhaust work can include rooftop duct sections, transitions, elbows, supports, fan connections, and related exhaust equipment. - Can an existing restaurant exhaust system be upgraded?
Yes. Existing restaurants may require replacement duct sections, rerouting, new transitions, fan upgrades, hood connections, or more extensive exhaust system reconstruction depending on the condition and configuration of the existing system. - Does Master Fire Mechanical work on older NYC restaurants and diners?
Yes. Existing restaurant projects are a major reason custom fabrication is useful because the exhaust system often must be designed around established building and kitchen conditions. - Do you coordinate commercial kitchen exhaust work with fire protection?
Yes. Commercial kitchen exhaust, hood, cooking equipment, and fire protection requirements must be properly coordinated when they are part of the same restaurant project.




Custom Restaurant Exhaust Fabrication & Installation
| Component | Function | Why Custom Fabrication May Be Needed |
|---|---|---|
| Hood Connection | Connects the commercial kitchen hood to the exhaust path | Must fit the hood location and available ceiling space |
| Welded Duct Transition | Changes duct dimensions or configuration | Adapts the exhaust system to actual field conditions |
| Square-to-Round Transition | Connects differently shaped exhaust components | Allows rectangular ductwork to connect with round equipment or duct |
| Rooftop Ductwork | Carries exhaust toward the exterior discharge | Routing must work around existing rooftop conditions |
| Duct Supports | Supports installed rooftop duct and equipment | Fabricated or positioned around the specific installation |
| Commercial Exhaust Fan | Creates airflow through the kitchen exhaust system | Must connect correctly with the installed duct configuration |

Commercial kitchen exhaust fabrication is often less about buying standard ductwork and more about solving the conditions found in the building. Existing NYC restaurants can present tight ceiling spaces, fixed hood locations, difficult roof penetrations, neighboring equipment, structural obstacles, and unusual exhaust routes.
Master Fire Mechanical fabricates and installs commercial kitchen exhaust components around those real-world conditions. Our work can include hood connections, welded ductwork, custom transitions, rooftop exhaust runs, equipment supports, fan connections, and related mechanical coordination.
Custom Exhaust Solutions Built for NYC Restaurants
The Cosmos project at 1952 Clinton Avenue demonstrates that capability from fabrication through finished rooftop installation. Rather than forcing standardized components into an established diner, the exhaust system was adapted to the kitchen and building.
For restaurant owners, contractors, architects, and property managers, that fabrication capability can simplify a difficult renovation or exhaust replacement project. It also gives the team working inside the kitchen and the team working on the roof one coordinated mechanical objective.
