Sternvent

What Sternvent does

Sternvent is a Union, New Jersey-based industrial manufacturer of dust collection and air filtration equipment, founded by Harry Stern in 1952 in Brooklyn as an industrial sheet metal contracting firm. Since pivoting to dust collector manufacturing in the 1970s, the company has built a portfolio spanning three core technologies — cyclones (centrifugal separation), shaker filter bag collectors (DG/DS manual and DK/Vibraclean automatic), and pulse jet cartridge collectors (SternPulse SPH horizontal and SPV vertical) — along with after-filters, mist collectors (MistCheck), down-draft benches, and PPO positive-pressure open-style units for NFPA 664-compliant indoor woodworking. Filtration efficiency is specified at 99% for cyclones alone, 99.9% for cyclones with after filters and shaker lines, and 99.99% for cartridge pulse-jet models. Capacity ranges span 400 CFM (compact DG101) to 24,000 CFM (SPH4-48), covering school wood shops through to continuous-duty industrial operations in metalworking, woodworking, plastics, pharmaceuticals, chemicals, food processing, and seed/agriculture applications.

The company manufactures in-house through a 2010 acquisition by Durex Inc., a Union, NJ custom sheet metal fabrication and stamping facility, providing CNC machining, powder coating, and assembly capabilities. Revenue is generated through direct, one-time equipment sales plus an aftermarket stream of replacement filters and consumable parts ordered through a dedicated customer-service contact (Francois Giliberti). Go-to-market is exclusively direct — phone (908-688-0807), email, and a website contact form — with no distributor, reseller, or marketplace channel; customers are consultatively guided to one of three technology choices based on dust type, CFM requirements, and duty cycle. The company's stated primary market is school wood shops, where it explicitly claims market leadership; secondary markets are small-to-mid industrial manufacturing and maintenance facilities, distributed across the Northeast and Midwest United States (NJ, NY, PA, MN, KY, VA, NC, OH, NH, IN, GA) with occasional enterprise references (Kodak, Steinway Piano, BASF, Kraft Foods, Harley-Davidson) dating to the 1970s.

Operationally, Sternvent is a small, privately held subsidiary within the Durex family of companies, with only two actively referenced personnel (technical support and customer service) plus the historical founder. Marketing is supported by downloadable educational resources targeting the architectural specification process and earned media in industrial trade publications. No patents, formal certifications, or external funding have been disclosed.

Revenue model

1. Dust Collector Equipment Sales: One-time sale of dust collection equipment. Sternvent manufactures and sells dust collectors across multiple technology types (cyclone, shaker, jet pulse, mist). Each unit is selected based on the customer's air flow requirements (CFM), application, and dust type. Models range from compact DG101 (400-500 CFM) to large CY4400 (8,000-12,000 CFM).
2. Replacement Parts: Recurring revenue from replacement filters, filter bags, and other consumable parts. Customers contact customer service (Francois Giliberti) for replacement parts. Includes spare filter media, plastic bags, and other wear components.

Core offering

Sternvent manufactures and sells industrial dust collection and air filtration equipment, including cyclone separators, shaker filter bag collectors, jet pulse cartridge collectors, mist collectors, after-filters, NFPA 664-compliant open style collectors, and down draft benches. The company serves industrial, educational, and maintenance facility customers across the United States with airflow capacities ranging from 400 to 24,000 CFM, plus replacement filters and parts.

Product overview

Sternvent is a manufacturer of industrial dust collection and air quality equipment. The product portfolio consists of three main dust collector styles (cyclone, shaker filter, and pulse jet filter) offered across multiple product lines. The core products include: (1) DG/DS and DK/Vibraclean models (shaker filter bag style for intermittent use), (2) Cyclone collectors (workhorse for medium to coarse dust), (3) SPH and SPV/SternPulse models (horizontal and vertical cartridge pulse jet for continuous operation and fine dust), (4) CCP bag style collectors (for heavy or non-free-flowing dust), (5) PPO positive pressure open style (for NFPA-compliant indoor woodworking), and (6) specialty products including After Filters for cyclone systems, Down Draft Benches, and MistCheck mist collectors. The products share common engineering principles (dirty air inlet, filtration, dust collection) but differ in filter mechanism, capacity range (400 to 24,000 CFM), and intended application (woodworking, metalworking, chemical, pharmaceutical, food processing).
